- 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...

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
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 was so helpful for a person who did not know this 3 hours ago
{з з в
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.
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.
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!
weak*
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!
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 was my first real dive into regular expressions. Today I am glad I started here. Great job!
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.
10 years of programming and now i can tell i know how to write a regular expression thank you so much
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 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!!!
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
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.❤❤❤❤
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. ;-)

Literally the one who managed to explain regex in a way "from zero to hero"
Thanks man! U`re doing a great job!
regex never become that easy... this man is very talented on teaching, even on tough topics.. just awesome!
There’s a reason this has a million views. Other videos just didn’t explain it as well as you did here. Thanks!
I just finished a day long class in regex and didn't understand it - watched this and now it's simple. Thanks mate!
This is THE best explanation of Regular Expressions available in the web!!
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!
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.
If someone understands the topic deep enough he can teach difficult things in easy way. OMG YOU DID IT AGAIN❤
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 :)
The best video for RegExp. I researched on this area, but not found better videos/docs than this video before. Thank you @Corey Schafer
I hated regular expressions before watching your well explained video. Thank you so much.
I feel like I am gonna cry tears of happiness 🥺 the best regex tutorial ever!!
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 !!!
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!
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.
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!!
omg, this is one of the best tutorials i have ever watched in my entire lifetime
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!
This is clearly the best RegEx video that someone has done in the history of man kind
Mr Schafer, I can't thank you enough for this tutorial.
You have so simplified the regex.
I liked and subscribed.
And here is the single best software developer tutorial ON THE ENTIRE INTERNET
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!
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.
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....!!
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!!!!
Incredibly well taught and organized video. Have never seen a video from Corey that is not outstanding. Thank you.
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.....!!!!!!!!!!!!!!!!!!!
One of the best you tube tutorial videos on any subject. Concise, quick, clear, just right length.
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!!!
Paused video and came here to say Thank you :)
why>?
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.
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.
Thanks a lot for making me realize that complex pattern matching is so simple. Cannot ask for better explanation. Kudos to you.
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!
Thank you, you're my God. My notes:
6:34 - Explanation of \b
22:44 - Explanation of groups
30:57 - More details on groups
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 !
Understood RegEx so quickly, loved this tutorial!
I was hating Regex but now I started loving them. Thank you so much :)
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!
3 years old and still gold, best video to quickstart regular expressions ! Good job
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.
You just demystified Regex in 30 minutes Thanks alot
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.
This was the best ever explanation of regex! The presenter is very glib and succinct. Never heard him use "um", "er" or other regular expressions folks do during presentations or conversations.
Not only you adroit in your field but a phenomenal teacher -the last of a kind.
Very much liked, understood regex, and subscribed.
Thank you for sharing your knowledge with us!
The only Regex video you'll ever need.
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 😁.
You did what my professor took 4 lectures to do.. truly amazing and splendid. Keep going my friend !!
This is one of the best explanatory videos I've ever seen in TH-cam.
excellet. Very well explained. Spent some time reading regex but you summed it all up in 30 mins. Great stuff
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.
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.
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.
First time learning regular expression. Useful and easy to understand.
very nice corey. well structured and explained, that was fun. keep doing this kind of tutorials.
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.
Wow!! What a great tutorial on regex. I'm no longer lost in the dark black forest of the lost.
The best video on this topic I've seen so far. Thank you!
The best regex tutorial I’ve ever seen. Thanks so much!
Absolutely loved it, never seen such simple explanation to a complex topic. Never felt confident reading regular expression before but now yes i can. Subscribing to your channel immediately. Watching this on my memorial weekend, totally worth spending 38 mins of my time.
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
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.
38 minutes very worth ,must see he covered everything about regular expression hats off man❤
I FINALLY GOT IT!!! I always read the tutorials and don’t understand what the hell is going on. Even when I practice and try out the patterns I can’t figure it out. I would just give up and look for a ready made regex online. Now it seems so easy!! Thank you so much. Very clear explanation with good examples. Organized tutorial and straight to the point. Just perfect👌🏻
Its been almost 5 years and it is still the best regexp video.
EXACTLY what I was looking for. Great explanation, thank you!
Extraction of tens of books in a single video, Helpfull !!!
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!
The world needs more people explaining CS stuff like this dude.
I wish all tutorials were this good
Really good video: i especially loved your pace. Keep up with the great work
this is by far the best RegEx tutorial i have found on the internet.
37 minutes 54 seconds well spent, very clear explanation. Thank you Corey Schafer
Wow really nice , keep it up , I am waiting for the advanced Regex Tutorial for sure ;)
Thank you for this great and simple explanation. Really helped me!
I was always scared about regex. I favorited this video a year ago, but only now I could prioritize it. Totally worth it.
I am so happy to have found this! I have been struggling to teach myself this and I just learned more from you in 15 minutes than I have in months. You teaching methods and explanations are so easy to understand. Thank you!
Fantastic explanation no one else can explain more clearer than him
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!
This is hands down the best intro to regex on TH-cam. I don't use regex on a daily basis, so this is my standard go-to refresher video! Always!!! 👍
its not just that you made regex look easy..... u kept me hooked all the time. I usually can't take more than 10 minutes of programming tutorials, but watched this one completely without getting mentally drained
A very nice explanation. Keep up the good work . Hope to see the advanced regex video soon . Cheers
