- In this regular expressions (regex) tutorial, we're going to be learning how to match patterns of text. Regular expressions are extremely useful for matching common patterns of text such as email addresses, phone numbers, URLs, etc. Almost every programming language has a regular expression library, so learning regular expressions with not only help you with finding patterns in your text editors, but also you'll be able to use these programming libraries to search for patterns programmatically as well. Let's get started...

38mins well spent, totally worth it.
Im a newbie. Dont know anything, but I loved your lesson. Hopefully I find more videos in the same direction, and as fare as I felt that I learn a lot, I hopefully find how to use it at the end.
I concur
This.
Spent 60 mins jumping from Stack post from another looking for a quick answer,
then decided that fuck it let's watch it the slow way and maybe actually learn something.
I watched three times
@@persvendsen270 You got lucky as you just saved yourself from struggling with Regex which most us did before this video !!!
This is really unfair to regular expressions, they are supposed to be difficult.
haha, yes bro. REGEX SHOULD BE DIFFICULT.....
so true.
@Roshane Johnson regex is like game of thrones
It still is for me. The examples are very basic. Try something more advanced and you will see.
Could not have put it better myself. I'm sure it gets harder but that was amazing
This was so helpful for a person who did not know this 3 hours ago

This was the video that made Regex go from “I hate Regex” to, “I like Regex!”
Still working on my Regex skills but I feel confident of solving scenarios to a high standard now.
You explained Regex in a way that is easy to understand and cover some really great scenarios.
I have screenshots from this video I still use :D
@@Steve-yq5fh Can you give regex expression for the below expression
iam good
@@kumarguru3044 need a full sample and information on the panel to give you a robust Regex pattern.
Whenever I see talented people like you giving perfect explanations I feel confident to say: things are not difficult, just badly explain. Thanks to you I was able to FINALLY understand regex and actually start looking at it very friendly. THANKS so much!
I stole my reply :) Nothing more to add
You got some serious teaching skills, Please make an advance series on regex.
Thank you
Please we need advanced teaching. This is super basic. Please make this guy upload a more in depth video!
Yes, I want an advance series on regex!
Yes, advanced would be great!
Advanced regex videos would be super helpful!
Yes, please... we all are waiting for advanced series.
There’s a reason this has a million views. Other videos just didn’t explain it as well as you did here. Thanks!
The more than 1,202 comments before mine have said it all....To cap it, i will say "you are the G.O.A.T of regular expressions."
I was in bad mood today , when i opened chrome browser today i saw a pop up that Coery uploaded a video about Regular expressions , I took a moment and realized that this is the area i am week . Started watching and as well as practicing , once the video is completed I felt it was awesome . I literally tried out the examples by pausing the video . I would like to thank you a lot , for sharing this knowledge. Have a great Day
Glad to hear you found it helpful! Hope you have a great day as well!

Hands down, the best instructor I've ever watched ... as a student, I have never seen an instructor who is so precise, concise and yet so easy to understand, hats off to you Corey.
I don't understand how there can be any unlikes on this. This was a life saver in trying to understand this as a newb. Thank you for opening my eyes!
This was my first real dive into regular expressions. Today I am glad I started here. Great job!
OMG. I am just 11 minutes into this tutorial and I have already found a solution to my problem...But I am just going to watch the rest of the video.😂
hackerrank problem :)
Right?! i got about 8 minutes in and my issue is solved. This is an extremely helpful video.
This is the best tutorial on regular expression I found online so far. I really like how you build up the knowledge gradually and provide real world examples. This tutorial is consistent with your great Udemy classes. Thank you Corey.
I know everyone in the comments is echoing this same sentiment, but I have to say this really is the best introduction into regular expressions I have seen online. Most tutorials throw you into regular expressions without explaining the basics. This is great!
I just finished a day long class in regex and didn't understand it - watched this and now it's simple. Thanks mate!
10 years of programming and now i can tell i know how to write a regular expression thank you so much
I was about to skip this video, but thanks to all the guys who commented. Worth my time. Learned a lot. Thanks, Corey. You are an amazing teacher.❤❤❤❤
I didn't realize there was a better teacher than you in this world. I love how you've managed to gradually build my knowledge from zero to hero. Thanks to you, I can now read almost any regex thrown at me. I'm watching this six years later after the upload, and it is still the best regex explanation I could ever hope for. Thank you so much, man!!!
I have been stuck on a freeCodeCamp challenge for days, I watched this video, and I solved the challenge. This is the best RegexContent on here.
And here is the single best software developer tutorial ON THE ENTIRE INTERNET
regex never become that easy... this man is very talented on teaching, even on tough topics.. just awesome!
This is clearly the best RegEx video that someone has done in the history of man kind
I hated regular expressions before watching your well explained video. Thank you so much.
Ever since I started learning Python, RegEx always kept me on a backfoot ....
BUT NOW .....
NO MORE scared of RegEx,
NO MORE baffling with RegEX.
RegEX DEMYSTIFIED !!!!!
THANK YOU SO MUCH Corey !!!
Mr. Corey Schafer this has help me in ways beyond expression! As a novice you help me understand how to edit my data in ATOM, THANK YOU!!
Literally the one who managed to explain regex in a way "from zero to hero"
Thanks man! U`re doing a great job!
Corey Schafer. You rock dude! I have been programming/managing projects/troubleshooting stuff for 18 years. I have never really learned Regex or even tried. They just bamboozled me. This one tutorial blew my mind away. BEST tutorial for REGEX ever!! Thanks
Corey, you obviously put in a lot of planning to create such a smooth and complete video, making a complicated subject seem simple. Outstanding job!
while searching for this topic, I came upon so many choices, didnt know which to choose, and couldnt believe my luck that I hit upon such a good video, which was generic and so well explained !
I feel like I am gonna cry tears of happiness 🥺 the best regex tutorial ever!!
Best regex tutorial I've ever seen! Always feel grateful with your amazing tutorials. Thank you corey! Also hope to see advanced regex tutorial later :)
Understood RegEx so quickly, loved this tutorial!
3 years old and still gold, best video to quickstart regular expressions ! Good job
Wow!! What a great tutorial on regex. I'm no longer lost in the dark black forest of the lost.
The best video for RegExp. I researched on this area, but not found better videos/docs than this video before. Thank you @Corey Schafer
This is THE best explanation of Regular Expressions available in the web!!
i was unable to learn regex from my college days . now i am a software engineer and regex is being used in projects. situation was very horrible for me. but suddenly i saw this video on youtube, i learnt regex very well ,also got confidence . i am very happy and subscribed this channel. Thankyou so much sir.
This is something I've been putting off for close to a decade - and it was actually quite simple, with the right tutor. Thank you Corey!
Thanks, I watched the whole video over the course of 2 days, taking diligent notes and got nearly a 100% on my regex test. I completely understand regex now!
Nobody understands regex completely. ;-)
@@timmwimmers6385
omg, this is one of the best tutorials i have ever watched in my entire lifetime
I was always scared about regex. I favorited this video a year ago, but only now I could prioritize it. Totally worth it.
Every time I go to a reg expression website I close it within 5 seconds and just give up, this video is great! Now I can tackle any reg expression documentation.
Oh oh! another wonderful tutorial from Corey Schafer! I've been avoiding this topic for a long time, in part because it was not that critical for me but also because every time I saw a regex I was automatically rejecting what seemed to me a completely random bunch of characters. But with this tutorial, from now on, no more running away from regex's. Thanks so much Mr Schafer!
Incredibly well taught and organized video. Have never seen a video from Corey that is not outstanding. Thank you.
why is it with corey's tutorial time flies by so fast? I get to the end of the video wondering if I need more because something complicated becomes easy and fast to grasp.
The best tutorial on the subject I stumbled on. Finally, I got the aha moment. All the credit goes to you. Thanks a lot for taking the time to share your knowledge.
Paused video and came here to say Thank you :)
why>?
To be honest, I have tried to learn regex for the past 6 years, without actually managing to do so. For the first time, I have managed to create regex to the email part. Prior you showing how to do, I paused the video and tried it myself. And guess what? I managed it! Much appreciated for the simple way of explaining!
This is an excellent tutorial on the basics of regex ! I don't usually comment on YT videos unless I find a really solid tutorial. This is one of those rare cases. Thank you for explaining it, breaking it down and demystifying regex.
The world needs more people explaining CS stuff like this dude.
This is perhaps the best video one can ever find on the internet to learn regular expressions. Everything is described in detail and in a way that people can understand clearly. Hats off to you. Thanks a lot for making this video!
Wow really nice , keep it up , I am waiting for the advanced Regex Tutorial for sure ;)
Its been almost 5 years and it is still the best regexp video.
You are a gem, you made regular expressions super easy to understand. We need more teachers like you who can make complex topics super easy.
Thanks a lot for making me realize that complex pattern matching is so simple. Cannot ask for better explanation. Kudos to you.
You sir have a gift. Same with the git tutorial, you literally upload your knowledge to my brain. Your voice as well is spot on. Quadruple thumbs up!!!!
4 years later, this tutorial is still very helpful for a person like myself to easily understand regex. After watching it, regex doesn't look to be too difficult to understand and follow.
25:16 my solution. [cC](orey|ore).?\d{0,3}-{0,1}[sS](chafer)@[a-z-.]+ I dont know if its any better, but Im very happy that I got my own answer. Thank you Corey for all of your amazing content. You have helped me alot.
The best regex tutorial I’ve ever seen. Thanks so much!
I was hating Regex but now I started loving them. Thank you so much :)
Mr Schafer, I can't thank you enough for this tutorial.
You have so simplified the regex.
I liked and subscribed.
It's not very often that one comes across a treasure on technical topics like this. What an amazing content really, so well prepared, so valuable, so rich and so detailed and yet to so simple. I thought I knew RegEx quite well but after this session, looks like there is still so much to be explored and used. Thank you so much. Great job, indeed....!!
The best video on this topic I've seen so far. Thank you!
I was trying to understand this term the whole day and I finally got to your video. I'm so glad that I did. Thank you ! you are my saviour 😁.
Having read a written tutorial on regular expressions, I found this miles better. Everything was crystal clear and explained in a logical order. First class!
One of the best you tube tutorial videos on any subject. Concise, quick, clear, just right length.
The only Regex video you'll ever need.
excellet. Very well explained. Spent some time reading regex but you summed it all up in 30 mins. Great stuff
Best video on the internet. I used to think regex is hard, but holy capsicum, this looked as easy as boiling water as the first cooking tutorial
These 38 mins saved a lot of hours trying to search for exact pattern on the internet during software development
I am so glad that I found this page. The video was perfect without any doubt. Please do an advanced Regex video if possible. Your channel is amazing as well.
Thanks!
very nice corey. well structured and explained, that was fun. keep doing this kind of tutorials.
Amazing! For somebody like me who knew nothing about what was or how to use regular expressions
this was so easy to grasp, clear and well explained. Thank you.
Dude, this video is so incredible. I watched at least 5 others and non of them explained so simply and clear as you did. I was trying to figure out regex all night for my program and you saved my life
I've just watched your video and then read the comments. What can I say that hasn't been said? Wonderful job, to the point. You know your stuff and you know how to put it through to people. You're clear and efficient (and your voice is pleasing to hear as well!). I used to be a French teacher for 18 years. I know, it is quite different stuff but I can recognize a good professional when I see/hear one. Pleaaase do upload the advance Regex video!!!
EXACTLY what I was looking for. Great explanation, thank you!
Beautiful. I've been trying to get enough of a grasp on them to actually use them not instantly search for an alternative. Finally I have crossed that bridge. You are a really great teacher.
If someone understands the topic deep enough he can teach difficult things in easy way. OMG YOU DID IT AGAIN❤
Literally exactly what I was looking for. I hope you get a decent cut from the sponsor button.
Thanks! I just put up the Sponsor button yesterday, so you're actually my first one! I really appreciate that!
Oh awesome! I've been watching your videos for about 3 months, since I started learning Python. Incredible stuff man. (I actually tried to set up a patreon but had some weird login issues with it) I've actually been struggling figuring out how to scrape phone numbers specifically so, this was dead on.
You just demystified Regex in 30 minutes Thanks alot
this is by far the best RegEx tutorial i have found on the internet.
This is one of the best explanatory videos I've ever seen in TH-cam.
Really good video: i especially loved your pace. Keep up with the great work
First time learning regular expression. Useful and easy to understand.
This video taught me everything my lecturer couldn't in 38 minutes. Thank you so much for creating this!!! You are helping so many people.
37 minutes 54 seconds well spent, very clear explanation. Thank you Corey Schafer
I’ve put off learning regex forever since it just seemed so complicated but you did such a great job simplifying it. Can’t believe I was reluctant to learn for so long; thank you for the tutorial!
In the exact same boat, I put it off for 22 years until today. Wish this video was around 22 years ago.
Great tutorial! People who are just starting out in programming, I have one tip for you. Whatever language you decide to learn, learn regular expressions basics on the side. You are going to run into them in the job environment.
Can't thank you enough. Was struggling with regex for a while but your video made it crystal clear. Thank you so much.
Man... I needed to pause the class to thank you. So so so much easier than I thought, I kinda had a hard time to grasp the concept, but now I'm getting how to use regex a lot better. THank you
Awesome!!! +1 for advanced regex tutorial
A very nice explanation. Keep up the good work . Hope to see the advanced regex video soon . Cheers
Thank you for taking the time to put together an excellent overview of Regular Expressions! You covered enough to get anyone started. Your teaching style makes it very easy to understand the core concepts. Using your examples, one can start assembling more complicated searches to solve more difficult problems. Please put together an Advanced Regular Expressions video.
This is the best explanation and tutorial on Regex that I have ever seen. I always say things are only as complicated as the person teaching it wants to make it.
Wow Corey, you just blew my mind :D - now i get it !
I study software at uni, and i did not get what he tried to learn me - but you did!
38 minutes very worth ,must see he covered everything about regular expression hats off man❤
Watched many times whenever I need to refresh my memory on regex, this is just the best one, concise and have everything I need, thank you so much Corey for your wonderful job!
You're are blessing to all those trying to learn regular expression and I appreciate you one thousand percent for getting straight to the point without all the BS. I wish more videos demonstrated this same effort. I will try to drive more people to your youtube channel to get quality content like yours. I thank you for providing the files you used so we can watch & learn with you. Thank you for adding clarity to someone who's has been lost trying to read someone's script with minimal success. Keep up the great work and I will keep watching.....!!!!!!!!!!!!!!!!!!!
Jesus, I had a look at so many written tutorials - felt stupid - found your video on a coincident, feel like Batman now!
