Regular Expressions in Python || Python Tutorial || Learn Python Programming

[@patricksweeney6334]

I absolutely love Ulka's ability to deliver the dry sense of humor that permeates these videos. "To use regular expressions with python, import the 're' module. After hours of research, we were unable to find what 're' stands for."

something happens, and then they profit

[@fredsmith6324]

uhuh uhuh uhuh...

[@LandOfSigh]

Some people, when confronted with a problem, think “I know, I'll use regular expressions.” Now they have two problems.

[@HarshitDaftary]

Great to see python videos again 😊

[@matthewwithum8372]

💯

[@massimo6767]

Hi! I was a first year student when i used to watch your python tutorials. Now i am a full-time Data Eng. and seeing your videos again makes me kinda nostalgic (in a positive way). Thanks so much for your work, your videos helped me a lot during my first steps ❤

[@Socratica]

We love hearing about where your journey is taking you! Thanks for including us. 💜🦉

[@TheoSophii]

Thank you Socrotica for these beautiful video tutorials

[@Socratica]

𝙎𝙩𝙖𝙮 𝙞𝙣 𝙩𝙝𝙚 𝙡𝙤𝙤𝙥 𝙄𝙉𝙁𝙄𝙉𝙄𝙏𝙀𝙇𝙔: snu.socratica.com/python Quick Note: In regular expressions, a dot . matches ANY character. So our URL regex, https?://w{3}.\w+ etc works, but could be greatly improved if we replace the . pattern with \. The \. matches only the period.

[@Allen-by6ci]

Ulka has perfected her character. More of her teaching everything. She's awesome

[@bassbacke]

I thought I had some idea about regular expressions but now I know there's so much more to the re module. Thanks for inspiring us to dive deeper into the re module.

[@nonominox]

Perfect timing, we're just starting with re in our Python class!

[@linghung9797]

How is it going? I’m starting mine this week

[@jagadishgospat2548]

I didn't expect it to be this easy to understand, thanks guys.

[@HexenzirkelZuluhed]

Great video. Note however that in the last examples with the URLs, you are using '.' to look for a literal dot in the URL. A single dot in a pattern matches any character. If you want to look for a literal dot, you need to use '\.'. Also, Python supports verbose regular expressions, that allow comments inside the code.

[@alexrubio9507]

very good observation there

[@sarundayo]

Glad these series is still alive and well :DD

[@aiforyounow]

Forever my favorite channel

[@martinus9755]

Great to see another one of these videos. They're clear, concise and the format is really fun.

[@gamorales]

RegEx is one of the most beautiful things that exists. Python make RegEx really easy and simple to use. 😍

[@davidawakim5473]

Love that Socratica is back! Y'all make the best educational videos I've seen in a long time, just binged the abstract algebra playlist and now hoping into more learning! Thank you!!

[@EuphoricRaccoon]

Seeing an upload of a Python tutorial with Ulka from Socratica once again after all this time made me incredibly happy. Seriously, all of these are a bloody gem

[@JANSENM9]

This is the reason I am a Socratica patreon. Thank you - there will never be too many of these!

[@Socratica]

Amazing. Thank you for helping us make these videos possible! 💜🦉

[@NikitaNair]

Such an amazing video... Very easily explained and effective for learning

[@brunosantos3672]

I'm happy to see a new Python video here!

[@rantalbott6963]

Add me to the people praising the "performance" (deadpan delivery and subtle humor) that makes these videos engaging and even entertaining. But I especially want to praise the basic design of splitting them into narrow topics and going into just the right depth. I've learned over a dozen languages over the last 50+ years, so what I'm looking for as I learn Python is not the "This is a bit. This is a byte. This is a loop" basics I learned decades ago. What I need is is answers like "How are lists different from C arrays?" and "How is regex matching different from Awk or Perl?". Last week I needed to do some input validation, and regexes were the right tool. A few minutes with this video showed me the Python way to do it without needing to wade through a lot of non-regex material. You're doing great. Thanks.

[@zeitgenosse]

12:01 This regex will also match https followed by colon, followed by two forward slashes, followed by wwwsocraticaorg. The first dot would match the s, the backslash w+ would match ocratic and the last dot would match the a. To circumvent this, you need to escape the dot with a backslash.

[@hellionaires_sniping]

By far the best channel i know for learning python. Thanks for everything!!! Unfortunately i wasted a lot of time watching confusing video´s from other python developers.

[@d0m2288]

Awesome resource, as usual. I'm debugging an API and traced the issue back to some bad regular expression in one of the controllers.

[@BrianStDenis-pj1tq]

I love Socratica so much. The writing, presentation and subject matter are awesome.

[@BrianStDenis-pj1tq]

Regular expressions go deep (really deep) - as in they are complicated and nuanced. This is an overview. The "corrections" explained in the comments are correct but maybe more useful for the next video on regex. I was going to suggest a video on regex module vs re... but that isn't a "learning" video, its an "advanced use case" video. Thanks Socratica!

[@waltertross3581]

I'm glad you correctly pronounced regex (not like rejex) , and used the correct plural of index (indices). It took me a bit, though, to realize you were ironical about being unable to find the meaning of re.

[@freckhard]

Hey there great video and finally some python again! I have an annotation at 12:12 to make: while the dot technically matches the dot in regular expression it stands for "any character at all" (including the dot 🙂). If you really need a dot (and not a hyphen or anything else) we would need to escape that as well with \. 👏 Happy Holidays Socratica!

[@Socratica]

Excellent point! We should have spent some time talking about the . pattern since it's so common. We'll pin a comment to make sure people understand the difference between . \.

[@Flashxyz123]

I'm glad to see this series back. I said only this week in a video that I was sad they were discontinued. I hope you do more.

[@SuperYtc1]

Also would be good if you did some JavaScript in this style.

Q: ChatGPT, please extract two consecutive vowels by using regex in python from following string: "Francois". A:.... Simple code problems do not need to be understood anymore, great!

[@ithinkthereforeitalk935]

Exactly my thoughts. The revolution's coming but not too many people in the comment section are aware of this😉

[@cuszco]

I don't think "do not need to be understood anymore" is the right approach to this time saving marvel, though.

[@oliver2671]

[@cuszco]

@@oliver2671 That's actually a good idea. Thanks :D

[@dieterweik6858]

Who knows. Perhaps "Hand-coded" will become a thing. Just like "Hand-Made". Then again... maybe not.

[@lawrencedoliveiro9104]

Here’s a handy one: “\b” for matching word boundaries. For example, using “\bi\b” to search through code for the variable “i” without matching parts of every single word containing the letter “i”.

[@volbla]

One sequence i find handy is \h. It matches whitespaces, just like \s, but \s includes newline characters whereas \h doesn't. Usually when i search through text i want to keep to one line at a time. edit: Actually disregard that. Apparently that sequence is not in python's regex module :(

[@JC-ds1jh]

Thank you I love your videos. I use them in my cyber security class to help my students with Python

[@foustcor]

Yay! Python's back!

[@pthube]

It is great to see you back..

[@angladephil]

Nice to see you again !

[@scottbiggs8894]

I deeply applaud this video, thank you! But could you update this for python 3? A host of regex no longer functions as specified in this video.

[@StevenHancz]

Correction @6:55 the regex is looking for strings that contain 'C' followed by word characters not string shat start with 'C' character. The regex needs the ^ prefix to make it search for sting starting with 'C'.

[@Socratica]

We were actually using this regex to look for any sequence of characters that starts with C, not strings that start with C themselves. Here's a case where some emphasis would have been a good idea, especially since so many of our examples used the ^ pattern.

[@NipkowDisk]

I think regular expressions are like oysters: you either love them or hate them. Personally, I love them as they really helped me to extract data from one file format and convert it into another for usage in a land surveying statistical analysis program :)

[@ncmathsadist]

Nice regex intro. Excellent!

[@dwla16]

Regex is very powerful but I've always found it easy but confusing

[@humanrightsadvocate]

1:45 /Fran/ matches the "Fran" in "Francois" and the "Fran" in "Francesco". The entire video is littered with inaccuracies that conflate partial matches with exact matches. As always, when in doubt, use regexr.

RE stands for Regular Expressions 5:00

[@XxKingfisherxX]

what does "?=.*" mean in regex? Expecting detail lesson.

[@chefboyrdee1]

Don't use regular expressions. Use parser combinators. Thank me later. Parsec is a parser combinator library for Python. User gdevanla has a nice blogpost about it.
