Never thought I'd be binge watching Python tutorials
Same! For FA!😪
We lived the same life
@@justindominic4831 the fuck are you on about. Are you admitting to a crime?
@@YouLittleBrick may be promoting his website, which literally don't work like it's supposed to
@@YouLittleBrick r u even learing programming why are u saying such as bad word in this here
been here for 7 seconds, already better than my college professor. don't waste money on a class for this.
pretty funny
Yes i too agree with you @Alex L
exactly why I look for these videos. I pay money to TH-cam search everything.
I love that your videos are FAST paced, CLEAR with no idle chatter and with QUICK examples that show every aspect of what you are teaching. Of all the Python tutorials, yours are the best. :)
Thanks!
this is what I call padding, they did it so they can monetize the video with minimum info.
Yes! "an executed function is equal to the RETURN value" brilliant! Finally somebody explained this to me! CodeAcademy failed to explain this, as well as other youtube channels. SUBBD
I have seen many tutorials about functions and all of them failed at explaining how a function works
Agreed. Return was very confusing for me and if someone had just said that at the beginning it would have made it easy to understand.
Yeah, same here. This guy was pretty good at explaining everything.
what software do I have to download to code on that?
I know the frustration of it and immediately I'm thankful to those videos where I got it and the ones where I didn't get it. What is most important is you now have it
Your teachings are thorough. Your teachings are complete, precise. Your teachings dispel confusions and brings-in clarity. So much of sincerity and totality in your commitment to teaching is visible in each of your video! I must applaud you. Take a bow... Mr. Corey!
Fully agree
Truest comment on TH-cam
His classes are best so far.
I find that sometimes certain truths/knowledge are assumed. For example, 7.33 - 7.36... "i'll just pass this in with a '.format' "...I was lost.
THE MOST NERDY COMMENT IVE BEVER SEEN XD
Who else is watching this in 2020? I've learned more from you than any of my professors during my college experience! Keep up the great work!!!
very professional, no "umm"ing, direct, concise, each point logically builds upon the last. Very impressed. I am progressively working my way through all of your videos. Thank you!
what software do I have to download to code on that?
@@otakuhigh8788 His first videos go over that. He's using Sublime Text.
how are you now
@@otakuhigh8788 use pycharm
@@otakuhigh8788 There are various IDEs and text editors which you can use to code in Python like Sublime Text, Pycharm, Spyder, Notepad++.. each of them has their own pros and cons..
just finished this 20 min lecture in 1 hour , your each word contains so many information that is way beyond the expectations ,
Thanks a lot Sir for teaching function
I've never used Python before in my life, let alone functions in Python. This explanation made everything clear as day. Thanks!
I can't thank you enough for how straight forward learning python has been since watching your tutorials from the very beginning. Thank you for posting these awesome tutorials. I wish i could provide more support to your channel other than liking and subscribing but once my finances improve, you will definitely be my first patreon subscription.
Thanks!
Corey, I'm working my way through your Python Programming Beginner Tutorials playlist. I just want to stop and say I'm so grateful that I found your videos. In addition to clearly having a deep knowledge of Python (and programming in general), you are *such* an incredibly gifted and skilled teacher. Thank you for putting such care into these videos and making them free to anyone who wishes to learn. You are making STEM more inclusive and accessible for everyone, and frankly that makes you The Man.
I've spent so much time trying to understand functions and you are the only one that has explained it clear enough for me to understand. Thanks for this!
My mind is clear and peaceful after watch this lesson. Finally i can understand others tutorials better.
Thanks for explaining functions in details. I needed this for long time.
I will forever be grateful about that
I thoroughly recommend having an IDE open alongside to code along with the tutorial. Really helps learn. I find by just watching a Python video I barely retain any of it.
This is how a beginner's course should be. Fast, clear and straight to the point with no new or confusing stuff that leaves one hanging. People would pay for your videos on a source like UDEMY and as a person living in a country with no online payment possibility I seriously appreciate you work. And the fact that it's actually an Englishman teaching the course is just cherry on top. Cheers Mr.Schafer.
The so long confusion about args and kwargs ended here . Crystal Clear explanation. Thanks Corey :)
Hi Corey, I’m learning Python and my lecture has a habit of making simple things hard, I’ve watched two of your videos and been able to get up to date, and you have managed to give me more depth and detail in 30 minutes where as I have had 2 hour classes and come out confused. Keep the videos coming they are a real benefit to people new to Python.
Video paused at 12:29, *mouth opened, *eyes popped, #MINDBLOWN at how you make this simplified.
Thank you so much. Prolly gonna binge-watch your videos all weekend.
2019 , I'm watching this and enjoyed it . Thank you Corey. That was thorough and awesome .
I was needing to know more about *args and **kwargs, thanks for helping and explain this arguments
This is great! I am new to Python and by just reading the book for my class I was having a hard time, but after this video I have gained a better grasp on how it all works! Thank you!!
The way the leap year is defined is beautiful. I would never be able to write that in such a clean way!
I'm glad I got to see this video. Cleared my difficulties with functions
6 years later and I am glad I found your tutorial. My professor needs to come intern for you to learn how to teach Python.
Thank you. I watched 2 other videos on functions and it didn't 'click' until I watched yours. Wrote my code and it ran successfully! Re-wrote it a different way and that also works.
Best tutorials for simple reason:
topic is nailed by explaining core of the concept and proving an example that needs a 'light-bulb' in order to be solved
the only tutorial which made me learn functions right !
thanx...
Glad it helped!
Bro same here. So much clarity now. Thanks Corey.
@@coreyms /yoER tHe beSt
Yes this has made things seem much more clear.
@@coreyms thanks for sharing your knowledge. It helped me a lot
Definitely better than most Python tutorials on TH-cam. Your description of the leap year function was very clear.
its amazing how i was able to pick up these concepts of functions and the various arguments *args and **kwargs, and really understand it. your explanations and examples are really good
Bro, I watched several tutorials but no one dived into args and kward before at this point except you. This channel should be saved at any price
Thank you, Corey. Every time I search on something about python, I hope I find a tutorial from you. You are the best.
The is_leap & days_in_month is one of the most beautiful examples of defining a function.
Thank you Corey for sharing this.
Your tutorial is very helpful for beginners, they are very structured and easy to follow, and thorough! thank you so much i hope to learn more from you!
Wonderful. Before I watch this video i check almost all the website but finally I watch yours and its explained me so easy and clearly.
Thanks for your teaching.
1 min on youtube > 7weeks in college ：）
Bro, I feel that. I've got a program due tonight that I'm speed running
GoJoshua007 hit those gold splits boii
To be honest I thought I was the only one facing this kind of issues at the university. I don´t know what is happening in fact, but I have a strong feeeling that the root reason of all these things is the way they usually teaching the subject. Most of them are stucked and they think they don´t need to chage their mind, because they are professor. Ancient mind to solve nowadays problems doesn´t work!!!
Yes bro..! You are correct..!
You explain much more detail than Mike's video, I have so many question after I watched his video.
This is probabely the best Python tutorial I've ever watched. Thank you so much.
yes
Best Python lessons on the whole TH-cam so far. Thank you!
Your style of teaching is absolutetly great. Similar to Andrew Ng from Stanford University. Clear and elaborated. Thank you for uploading this.
Do you understand his Chinese accent? >
Great tutorials. You manage to explain everything so well unlike some other courses!
seriously man you're the best. NO BS and fast..
Thanks Corey, I am progressing in Python, and I am loving it, every minute of the teaching. And because of your teaching I am loving Python too.
Please make some competitive programming in Python too, if time permits.
def stands for "define", Thanks for the tutorials best on TH-cam ;)
the most explicit tutorial that i ever see!!! you did a very good job sir!
Crisp, solid and well paced explanations. These videos are a godsend, thank you for making these.
One of the things I appreciate is you help us understand the little nuances - like the difference between printing "hello_function()" and "hello_function". I always wondered why I should have the brackets at the end.
Thank you!
Is the function name with out parentheses like a C pointer to an instantiated version of the function, or something like that?
@@edmel144 From how I understand it, writing the function without parentheses is a reference to the function itself as an object (as opposed to calling the function for use). Therefore, printing the function without the parentheses gives details about the function object, its location in memory etc.
That's how I understand it.
I scroll only to find others comment the exact thing I feel. It's good to know that the feeling is mutual. Your videos truly are the only Python videos worth watching on this site. People actually understand what's going on. Keep up the great work!
Thanks a lot Corey!, I'm getting more confident in understanding Python, by watching your videos. Your explanation are excellent and very much in detail.
I'm a manual tester for more than 5 years now and I'm planning to transition to automated testing. I found your videos and I immediately got drawn to them. You're awesome! After finishing all of these, I hope I can start with learning Selenium Webdriver using Python. Thank you very much!
hi herald, how is manual tester as a career?
I feel like you could explain toothpaste leaving a tube and it'd be articulate and sound cool. Thanks a lot for this video, it's helped me a lot.
This part right here, especially the meaning of 'return' is a point I often got stuck on during my previous attemps at learning python. But I understand it incredibly clearly right now.
Awesome you have it all, you are the Best Teacher I ever had! Thank you, Mr. Corey
"Its not important you understand how a leap year is calculated" Zybooks expects you do know the equation in a lot of instances, which makes it harder to understand how to get to said outputs. Your videos have helped as a refresher as I'm at the end of my python course. I get most of it, I can't write it to save my life. I hope after watching these videos, I'll be able to churn out code easier from word problems I've been presented with. Thank you for for these lessons.
Thank you. Liked your video and subscribed your channel. I see that almost all mentioned about your excellent teaching method which I completely agree, and also your voice quality brings the much needed assurance that 'you can learn to code too', very few seem to notice this. Thank you once again.
Liked, subbed, turned on notifications! I finally understand functions a lot better now, thanks to the way you approached the subject in this video! Thank you, you're amazing!
It is very hard to get nice teachers like Corey Schafer in ordinary schools; mostly we got a bunch of mediocrity services in many schools including some that are very expensive. Mostly I have learnt many of computer applications, hardware and programming skills thru self learning using beautiful skills from nice people like Corey;
They can explain something in 21 minutes and you learn everything that could take you a year and half without understanding while in many schools.
kudos Corey; keep it up.
thanks for this i completly forgot how to use the def function you reminded me great vid dude
This is by far the best python tutorial I’ve seen. Thanks and great work!
finally I understood what the purpose of these stars is :D Thank you!
comfortable learning experience! I have watched dozens of coding youtuber and you are the first one who teaches *args and **kwargs in the function part.
The way you explained function was amazing, props to you!!
Your tutorials are amazing! Thank you for all of your job!
From someone who has digged many yt videos about how functions work, you nailed it
Thank you so much Sir,
your tutorials are awesome. I had to recheck if am subscribed because I cannot imagine missing any videos.
I am getting every concent in black and white.
I loved the explanation of *args and **kargs. hoping if u could make a vid on how a python experience guy understands new things or what happens in their minds (how they understand things and read Python codes) when a new version of Python releases or any module to understand its function and bring that to use for projects.
Corey , always been a fan and your channel is helping me a lot . I just have one thing to ask can you make some videos in which you discuss some standard practice questions and some great projects ; that would be very helpful . Again thanks a lot !
The explanation is so simple yet effective.
Thank you Corey for your time and effort. Keep spreading the knowledge.
OMG, dude you are freaking amazing. Your friends are lucky to know you. Subscribed!
I love how easy you make it. My teacher couldn't completly explain what is the difference between "return" and "print" in functions. Like here I got it right away.
subbed ofc
Thanks a lot for such detailed video about function !!!
Everything explained in details and depth with simple to understand.
Thanks a lot Mr. Corey Schafer. Your video's very helpful and helped me out more than my college professor.
I liked the example at the end, it was very helpful.
Best video about Functions on TH-cam. Very helpful and it clicked straight away. Subbing now.
One of the best explanations Ive seen so far easily
I am from Egypt and I enjoyed your explanation and learned from the video🔥
you are so descriptive in these tutorials , love it
Such a nice way to teach ...Cleared all the confusion regarding UDF .. Thanks a lot
wish i had a tuter like you. you are a great teacher 👍
Sir, excellent tutorial. Thank you.
You're the best tutor ever sir, believe it. Your work is much appreciated sir
i dont know English that much but this tutorials is the one of the best that i understand the most even though my english is less but this tutorials has never left me confused
Awesome! Glad to hear that!
I was not understanding functions, but this video was so helpful. Thank you a lot.
The best channel I ever found for self learning coding, it is just great!
Great, clear, and concise video. Thanks!
This is a true gem. Thanks Corey.
Thank you! I was confused about my code but you've helped me fix it :)
The best explanation I have found, and it is free! Thank you sir
I don't just to leave comments, but I had having troubles with this syntax for a week and I just crossed with you videos now and everything start to get clear, thanks a lot!!!!
Glad to hear!
The most satiating and complete tutorial on youtube. You are the best..
Thank you Corey, you make learning really easy!
Really amanzingly explained!! Congrats and Thank you for your noticeable effort
Finally Understood Functions!!
Thanks mate
! You teach in style!!. Thanks great man!
thank you!! functions are kinda hard but I'll watch it again and understand :), your classes are amazing
Very informative and exciting. Thanks
Instantly subbed after watching one of your videos. This is the best Puthon channel I've seen. Keep up your Great work
Thanks!
I've taken quite a few Python courses (some paid) and I must say none were as good (clear, understandable, to the point) as what I've seen here. Much of this is review for me but even so I found myself picking up some things I didn't know before. Looking forward to viewing all of your videos. Thanks Corey!
Thanks!
The reason I have chosen to self learning/teaching using such materials than paying my money to mediocrity services from those wannabe schools. Total waste of time from actually skilled teachers but who can't explain it in simple terms like mr. Corey; Barry Brown and Dojo; so far these three are my best tutors in coding.
Your explanations were simple. Subscribed. Thank you Schafer!.
And thanks for the tutorails,they are just incredible!
