If __name__ == "__main__" for Python Developers

- If name equals main - then we run our programs!
But do we actually understand what is _name_ , what is _main_ and most of all - why do we need to check if they match? 🤔🤔🤔
I've prepared this very special tutorial that dives deep into each component and demonstrates it thorough simple code examples. By the end of this video - you'll be able to explain this expression in your own words (!!!) as well as other terms like "module" and even "top level code" 😉
⏰ TIME STAMPS ⏰
------------------------------------------
00:00 - Intro
00:29 - What is _name_
00:59 - What is module?
01:34 - Top level code vs imported code
03:35 - What is _main_
05:08 - Find the value of _name_
05:55 - Why do we need to check if name == main
08:08 - Thanks for watching!

The most gorgeous python teacher with most synthesized way of teaching, keep it up
Did you guys watch the video at all before commenting? Please watch it. That's how you will learn. She is here to educate, not for fans.
Well dude as is know the Internet the Most dudes are Here , an i hate to say That cause sexism is Not my opinion but she is a attractive Woman and the Most Boys going Crazy if they See a beautyfull Girl on screen … its like twitch Girls … youre right she is very competent and i learned a lot from her
She’s hot AF that’s why clicked. But I stayed for her enthusiasm, knowledge and style of teaching.
@@htruth1785 Mhm you Need to know when its better to shut up and keep fingers away from keyboard… but thanks for the next men That keep this ugly aditute and the cockbrainer style… how u get Into IT with 3 mumbles That Collide uncontrolled ? Please… sit and go for pornhub … 😓
Don't worry Anthony, it doesn't mean they don't watch it, they just choose to comment on my looks instead of the content 😊
I don't really have a problem with that - I'd always take a subconscious learning process over nothing! hahahaha they don't notice but the info still sinks in 😅😅😅
@@S3R43o3 What many women consider sexism nowadays - used to be called courtship, and it was a very desirable behavior 😉
Nowadays it's "how dare you compliment me?? this is so disrespectful!!! I'll go complain to my 70 cats, they understand me so well..." 🤣🤣🤣
I like it when youtubers describe their code(s) verbally as they go along. For a blind person such as myself, it is of great help, since screen readers normally don't speak the contents inside videos, only in their descriptions, so if you say what you are doing while you write/show the code, the explanation becomes accessible!
Thanks and keep up the good work!
Please don't take this question as offensive, as I am only intrigued, but you program while being blind? Is it actually doable?
@@WhiteNight0204 I am not an expert in accessibility features, but I remember from my time at apple that on a regular blind or visually impaired people would come in to give their Mac to service. They were able to fully control their computer due to the accessibility features and additionally there were experts in the store that knew how to use these features. So I guess as long as you can control a computer you can program on it.
@@RAP4EVERMRC96, thanks for the help in replying! I will add that while blind people might not be the greatest in GUIs in terms of object positioning, colors, etc, we can definitely build working functions and even deal with oop. Also, the screen reader that comes with Linux/GNOME - Orca - and one we use on Windows - NVDA - are both programmed in python! And as far as I know, NVDA's original developer - Mick Curran - is blind.
I myself am not a professional programmer, but like to learn something on Codewars, Exercism, etc.
Rock on, my guy. You are an inspiration.
@@rikkilleen3169, I will consider myself an inspiration when I become more than a newbie programmer, but thanks for the motivation!
This is the best explanation of this boilerplate code I had watched so far.
Thank you so much! glad you liked it! :)
you've achieved mastery in clean, logical, and engaging explanations of programming concepts. my understanding of the topic has increased substantially. thanks so much mariya!
Are you for real? This is the best explanation out there!! Contains everything i ever wanted,why its used and what it is doing! Thanks sensei!!
This was actually way more insightful than I expected... Thanks, great explanation!
So thorough with great examples/visuals! Great job 👏. I look forward to more.
Excellent explanation! You have included some essential features of this statement that makes it all so much more understandable, unlike many other explanations I have seen on TH-cam. Thanks!
I’m really enjoying your videos a lot. I’ve been wondering why I write that exact line of code for weeks, with no clue as to why. Once again, you nailed it! Your way of explaining things in a digestible manner for a total beginner is unparalleled. Thank you for sharing.
The example at the very end with "from import_me import call_me" that showed it running the function just because it was imported, really helped me solidify the concept. Thank you! And thank you for all your quick videos on good python habits and explanations like this. They really do help us get through some of our projects after we've been out of the game for so long.
I have been wondering this for ages, thank you for breaking it down so simply. You are the best!!
Thank you Richie! I'm super happy you found it helpful! 😀
I used to scroll down and pass your videos but now i am hooked as your methods of teaching is really easy. Thanks again
As always, the best and cleary explanation from entire TH-cam platform. Thank you so much!!!
Amazing content! Pleeease keep it up! You built it up like a crescendo and suddenly became crystal clear why this "if __name == __main__:" stuff is so necessary.
If only everyone could explain things as clearly as you do. Nice job, thank you.
This was such a good video! I've always been curious about this, but never really looked it up. Now it makes sense :) Thanks for the clear explanation!
This was actually a brilliantly executed lesson plan! Profuse thanks to you.
Never thought I'll come across such content on TH-cam and for absolutely free of cost oml, once again I'd like to screech out loud, this is straight off GREAT!
I am a French developer, beginner in python, and your tutorial is extremely clear, I understood everything!
I often avoid English tutorials because the TH-camr speaks quickly and I have trouble following but here I have nothing to complain about, your English is simple and easy to understand. I subscribe to your channel +1.
Thank you very much for this wonderful work. This is the first time I've posted a message on TH-cam in my entire life 😂 but it's well deserved !👏🙏
So much quality in this video. Simply perfection. Even thought I know a lot about if __name__ == '__main__' I found an additional information I've never know.
this is by far the most professional guide I've seen on this topic. this girl is serious
excellent explanation! I already tried for longtime to understand the basics of this statement, not only demonstrations of what happens with or without it. Thank you to spend more time than others to explain this for beginners: it is really helpful!
I just clicked this video bc I started learning Python yesterday, I have never seen a if __name__ = "__main__" in my life, yet you managed to make me understand how this works and why is it this way.
I found this super helpful. Watched a few explanations of the name = main thing but this was the first one that made perfect sense. Thanks so much !!
Great video. Thorough yet succinctly presented. Awesome job 👍🏻
Wow! Your channel was recommended to me a few months back and I kept passing it. Glad I finally watched 1 of your video. You’re such a great teacher. You make complex stuff simple. Thanks and will watch more videos from you
lol same
Your explanation is super great!!! I haven't anywhere seen such a great explanation, in my mind makes your teachings remember quite easy. Thank you so much and please continue making more and more videos for the world.
This is the first video that I watched from your channel, and I love your teaching techniques
I'm new to programming and I've already started learning python, this is the first video i watch on your channel and I'm amazed by how you simplify the information,
Thanks a lot and keep going
I like how you slow down and try to speak as clearly as possible! Great info, thz!!
Much appreciated. I always enjoy tutorials that provide the rationale for doing something rather than just droning on about how to do something.
I have to say, the last chapter (the example) was the best presentation for this guide - now it makes sense. TNX!
Your lessons Mariya really worth every seconds spent…watched dozens of videos regarding this topic (if __name__ == “__main__”…) and for the very first time I understand what it does actually 😄 thank you, thank you, thank you
Yeeeeeeyyy Emanuele, I'm so happy to hear that!!! 😀
For a very long time I understood the general concept, but after making this tutorial - you can wake me up in the middle of the night with a surprise quiz - and besides me being a bit grumpy I'll probably get an A+! hahahaha 🤣🤣🤣
Anyhow, I really enjoyed making this one and super glad you found it useful! 😊
thank you! I finally understand it simply. You do such an amazing job breaking things down without being condescending like others do.
ahhhh,,, this is the best channel for python i think. Clarity of voice , compression in sound, great examples and graphics and fantastic teaching skills!!
Out of all the TH-camrs your explanations really are the best!
Just found this channel. The content is great. Love python! Thank you for making these videos
I can understand everything you say easily. Your accent when speaking is very clear and easy to translate. The explanation is very clear and specific, thank you. 👌🏻
Best teacher on youtube ! I can follow your code and you make all easy to understand, and what a Beauty too!
Holy moly! Two days ago I was figuring out what this idiom was for and now you post about it, it's amazing.
I caught you at the perfect timing!!! 😉
Thank you so much, Otar!
I'm purely amazed by your explanations! I only had to backtrack (a bit) once to understand all of it even though I'm still a beginner. You are the hero function we needed to call! 😭😭🥺❤️🙏✨
Yeeeyyyyyy! Thank you so much for the incredible feedback, hiutale!! 😁😁😁
I always enjoy reading your comments and I'm super happy you find my videos useful!
A few more Python projects to experiment with - and you'll be able to ditch the beginner status in no time 😉
What a super wonderful and crystal clear way of explaining. :-)
Thanks lot Mariya!
Thank you so much Rune! I'm super happy you enjoyed this tutorial! 😃😃😃
I haven't heard such clear and beautiful English pronunciation in a long time
I watched around 5 different videos about it but never understand it. Finally, now I get it.
Thank you
The best explanation I ever seen so far on this topic… Thanks!!!
Girl i I'm love with your content and with python thanks to you. Nice work! You explain very well. Usually i watch in 1.5 speed but with your videos i dont even need that because you explain in the perfect speed. Keep up the awesome work!
I've seen many videos explaining ( if __name__=__main__) and frankly, this is the most understandable one. thanks
Jesus that was so damn clear. I actually understood it without rewinding it. The examples were so crucial and clear. Loved it!
A very clear, concise, and well presented lesson. Bravo.
you always go beyond the things i expect to get ..much love Prof
I learned a lot from this. I had seen the code described, but never fully understood. Thank you.
I didn't know about this before, you attracted my attention, first I hot confused, but at the end you finally solved everything. Thanks teacher.
SO clear and concise. Thank you!!
This is the best explanation of if __name__ == '__main__' that I've seen to date. Thanks a lot! 🤗🤗🤗
Thank you, that's the best explanation of how this works that I've found...
OMG!!! I can't believe I never really understood this until now. THANK YOU for this video
I have to admin Mariya you're the best. I have been a developer for 25+ years and I'm trying to learn Python this late and only your tutorials make a lot of sense. I might me a Python programmer ONLY in the future if I go through all your numerous videos! Thanks Mariya.
Amazing explanation. Thanks you so much! Thumbed up and suscribed, this was amazing.
Great explanation! I originally misunderstood, and oversimplified. This helped straighten out both problems. Excellent channel, by the way!
Wow, you explained it so clearly, thank you!!
such a brilliant video/explanation! i'm starting to learn python and i've ran into this if __name__=="__main__" 2 times already and didn't really understand it.. now i do!!! thank you very much!! (and this will sound very random lol but you have a great speaking voice!)
Great explanation, I had this explained to me before but it wasn’t entirely clear, and this makes it much more clear. Now I totally get it. Thanks, great resource!
That is the first time I understood that. Thank you so much for being a great teacher.
Great video. Good to see coding videos that really define things properly. Which is in my opinion the best way to learn
OMG! Thank you for explaining it so succinctly.
That was very well explained. An incredible amount of work goes into eight minutes of content when you want it to be clear and concise. I really appreciate the effort. Thank you! 👍🏻👍🏻
Thank you so much for pointing it out Renato! 😀😀😀
This video was 2 weeks in the making and I kept re-filming and revising it until I was 100% happy with the results! (it happens rarely! usually I'm ok with 95% 😅 hahaha)
I'm so happy you liked this tutorial and you appreciate all the hard work that was put into it!
Thanks again for the incredible comment! 😊
@@PythonSimplified I'm really happy that I got the opportunity to point it out! ☺
Much of the time, people just consume without considering the energy that is necessary to create something excellent. Whenever I notice the lengths that someone must have gone to in creating something exceptional, instead of giving in to mediocrity, I try to let them know that I know. It needs to be said and more people need to say it!
So, once again, thank you very much for the wonderful product of your exemplary work ethic! 👏🙏
The minute this video finished - I subscribed and gave it a thumbs up.
Marvelous explanation, thanks for this!
Thank you very much to you and youtube for suggesting me this content.
I could listen to hear all day...so well spoken & helpful
Over 10+ of python experience and I’m a proud active fan and follower. I love your teaching style, contents, personality and simply everything about you. Thank you so much for everything ❤
Wow, Alaa! Thank you so much for the incredible comment!!! 😀😀😀 I'm honored to have you onboard and so happy you enjoy my videos! I still have lots of things to learn, and getting feedback from professional developers with so many years of experience is one of my favourite perks in running this channel! 😉
Thanks again and I hope to see you soon in future videos! 😊
Totally agree!
last minute explained me everything! Thanks
Awesome as always. Thanks for the clear explanation with examples. Very easy to understand 🙂
Love the examples, they really helped make it click
Man, you're Best!!! no one could explain so well
Instead of watching my normal binge videos, I binge your videos. Your content is amazing.
Bella e brava, complimenti!!! Ottima insegnante
Clearly explained, I loved it!
I felt so illuminated at 7:35 LMAO.
Thanks for the fantastic visual explanation!
Thank you! Your video explains the concept really clearly!
Great vid! Super clear explanation! Thank youuu!!!
there cannot be a another great explanation than this .superrrrb.❤liked it
truly amamzed by the explanation, had some idea regarding __name__ and __main__ but never knew there were so many other things to learn such as top level code and top level environment. Many thanks Mariya :)
Thank you. I was just looking for information on this topic. And you recently released a video. Exactly what is needed!)
I would like to hear about "poetry" in the following videos. In particular, about the work of scripts through a short name, for example, as "poetry run short-name-script"
Wow. Crystal clear explanation. Instantly subscribed.
One of the most helpful videos on this
Very clear! many thanks Mariya!
The best Video so far on TH-cam. Thank you my colleague for the amazing
I actually figured that much but never bothered to actually look it up. Now I know for sure thanks
Thank you for addressing this information. I am about 20 days into my 100 days of code journey and i was wondering exactly what the __name__ module was as well as exactly what modules were. Thx -
🦋 💎🔥✍
👍 best explanation of the __name__ variable have seen thanx
I really enjoyed watching your video. I like the way you break things down. Thanks.
Well explained again ! Thank you very much 😊
Mystery has been solved thank you. Way easier than the explanations on forums like Stack overflow.
Thanks a lot for that explanation, the best one i've seen so far!
You saved me. Now I'm able to understand the use of __name__ == "__main__"
fantastic! Very clear indeed. Thank you!😀
Very well explained! Thanks👍👍
Very well done. Thank you for the effort you put into this tutorial.
I leaned C a few years after it was released and then C++ to write GUI programs for Windows 3.11 on MFC 1.0. The topic of this video is the thing about all previous programming languages that I always felt was missing.You present it a very clear manner.
Or a good sensible syntax and entry point handling function called main, just like in C, C++, Rust 😂
@@CallousCoder main was certainly in C and well structured assembly language programs, Python rides on top of a gold mine of C libraries that do everything you need. The difference IMHO is that when you have a file based module in Python it is syntactically and semantically handled the same as any other library unit. That is my point and that is what I always missed in C. C has always given you the ability to code as callously as you wish. But you should know that.
My Python program entries are always the same. Just like a well written C program
What was not mentioned here if you do not structure you code like this you are running the risk that __del__ for class instances may not get called.
def main():
result = 0
return result
if __name__=="__main__":
exit(main())
