[@Sri-wg3ne]

I don't understand how majority of the comments say that this explanation is better than a 30 minute video, I don't think anyone who didn't know regex concepts earlier would comment that!!

[@Harmless_creature]

it's a good intro of the topic .

[@Sri-wg3ne]

@@Harmless_creature Good refresher for people who already know regex basics. Definitely not for new learners.

[@rongarza9488]

I came here because I was overwhelmed with 30-minute explanations. This worked for me. Look, everybody learns their own way. If one source "doesn't talk to you", try another. I subscribed. Maybe later I'll feel more comfortable with 30-minute sources.

[@Neo--X]

Thank you for providing such a simple and straightforward tutorial. One point that stands out is your suggestion to use the expression finder feature to test search patterns. That is brilliant and will save us a lot of time as we learn to code.

[@caffeineTX]

Thanks for the breakdown, the script example was also really helpful.

[@vignesha6942]

Finally I got this in recommendation after 1 year. Thank you.!!

[@firSound]

This is not only one of the best intros to regex in python I've seen, but it's also a great ad. Makes your product look phenomenal without being intrusive. Truly you deserve an award for this marketing genius alone. Looking forward to giving kite a whirl.

[@KiteHQ]

Thank you for the kind words! We hope you love using Kite.

[@docmalc47]

@@KiteHQ I agree with fir Sound... great ad promotion with USEFUL content for anyone while demo'ing your product with a subtle mention. And all done in under 6 1/2 minutes. I'll download and give a try just based on principles.

So precise and so on point! Thanks a ton.

[@storiesbyasim]

0:58 If you're looking for the same thing on Mac, press Command +F and then check the third icon right next to the search bar. A minute into the tutorial and the Visual Studio thingy is the coolest thing I learnt today. Thank you. Relatively new to the community but love how we keep making each other better.

[@Susanajoan]

Now i know that i don't know. But it is good to see some useful example

[@Captinofthemudslayer]

Question: I have the following regex and text and i would like to match all doubles. However when I try to match them all it skips the 2nd line. How come? Note i am working in bash via mac terminal. what flags should i used besides -o and -i ([a-z]+) +\1 Paris in the the spring. The theoretical viewpoint is of little value here. I view the theoretical viewpoint as being of little value here. I think that that is often overdone. This sentence contains contains a doubled word or two two. Fear fear is a fearful thing. Writing successful programs requires that the the programmer fully understands the problem to be solved.

[@shashanksingh9118]

Hey man , could you make a video simply like you explained what /d and /D meant for every regex

[@uwugamer55]

I don't know if you've found the answer in the time between you posting this and this reply but, the lowercase is basically a "not" for the argument. /d looks for any digit 0-9 but /D looks for everything except 0-9.

[@swtpeteswtpete1515]

Very useful but needs added closed captioning warning that email match is generic, basic example, leaves out a lot! After the @ symbol you could have a hyphen or more than once included and or you could have digits 0 through 9. Also, isn't there a re search to match beginning of line or beginning of word etc? Just some constructive feedback.

[@luisorellana7622]

URGENT PLEASE: how can i do to add a word and a slash like this (/hi) to a found regex? i need this "/hi" before this regex \b\w{5,5}\b . if someone puts a name with 5 characters in it it must find that 5 characters name witch it does but it has also to add /hi infront of it as a result when it finds it

Sir how can we extract XML from a object column in dataframe and store in in a new feature in dataframe.

[@esmeraldaklahr5484]

Hello, I have a question, and I am hoping you have the time to answer fairly quickly. I am currently trying to help my boyfriend who is going through school for software engineering. Basically, his current teacher changes the outcome if the script isn't correct. So the challenge is, substituting a substring withing a list that is within a file using python regex. Is anyone at all able to show an example to do this that is most correct?

[@MichaelSmith-yh9zn]

Everyone keep in mind if you are an avid gamer and happen to play call of duty warzone in your free time that the program Kite that is recommended here will cause the game to consistently freeze and crash. Real fun time figuring that one out.

Man sucks Kite is no longer... anyone have a good alternative? Looked like a powerful af extension

[@tonyroaster5749]

I use kite and its asom

[@ryankhart]

Warning, don't use this regex for an email address in production. It is incomplete. Email address can include '+'s and '.'s before the '@' and possibly more. If you used this regex, you'd make many Gmail users angry especially with the + sign which is used so that users can add anything they want between the + and @ so that if they end up getting spam coming to them addressed with that unique identifier, they know who to blame for selling their email address.

[@jpcabral6567]

...I know Kung-fu...

[@spencerlawrence5323]

i hate how useful regex is, it's just so weird to use x.x

[@mikoajsawicki4488]

The pattern given for email validation is vulnerable. Consider passing there something like this: [e-mail]_LETTERS_OR_ANYTHING_ELSE_THERE. The simple solution is to add '$' at the end. "[a-zA-Z0-9]+@[a-zA-Z]+\.(com|edu|net)$"

[@psyoptic]

whyyyyy why did you make him read text on camera instead of actually walking through running the code himself? Production quality is one thing, but connecting to an audience is totally different.

[@jpeg.600x2]

is cool

[@nwachiikechukwu]

No way this helps someone who doesn’t know what regex is beforehand

[@loaf_loaf_loaf148]

why is kurt cobain/jason lee trying to teach me about regex

[@danielchacreton2401]

Just a suggestion, move your camera or turn you computer so that the camera is facing you head on. Looking at the side of your face is a bit distracting. Great video though.

[@keifer7813]

Nicely structured but way too fast. So many things going on that weren't explained clearly imo

I don’t like how you’re not facing the camera while explaining. I know it shouldn’t matter but it’s making me uncomfortable
