Neural I have been following you content for a while. It always good

The difference between re.search and re.match is that re.seach matches a pattern anywhere in the string meanwhile re.match matches always at the beggining of a string, so is essentially re.search but with an automatic ^ sign. Also, for matching a whole string exists re.fullmatch, which does the same as re.search("^(...)$", text), although I prefer just re.match("(...)$", text) which is shorter.

Thanks very much for covering all the required content in minutes.

Took a course and understood nothing about this concept. Saw your video ONCE and I understand everything now!

6:20 I believe "search" search for any occurrence of rule (a-z) in the string and "match" search for every occurrence a-z (so when it finds any capital letter (not only on the begging) then it returns "none")

man wow thanks. Easy and fast, right to the point, especially on 10:00

I am python learner from commerce field. I could understand it in first go. Thanks Bro <3

[sebastianmartinez]

Don't mind me. Just taking notes on the comments because I don't have my notebook with me:

^something$---> the string can only be composed by the something between the ^ and the $.
^something---> As long as the string begins with the something right after the^, you can add whatever you want afterwards.
something$---> Same but the something has to be by the end

check 11:50

Love your vids, keep up the good work!
and I need some tips because currently I am learning Python and I know the basics and have worked on some projects but don't really know what to do next

[christofervega]

Thanks, I've learned a lot from this video
One question, what is the theme you use? In pycharm when I try to write strings, everything comes out green and it's difficult to differentiate

6:50, I see you struggling a bit with the explanation of the match and search functions. The search function will look through the whole tring for anything that maches the given partern, whereas the match one check if the provided string 'matches' the partern, kinda like a strictly equal but with paterns.

thank you very informative and good video, better than my professor

[jesseluinstra]

Thanks! for introducing and making sense to REGEX

[dhruvdonsahu]

bro was rapping towards the end...
btw great video

[mehdimojaradi]

Thanks indeed for your efforts and sharing great contents. I am learning a lot from your channel.

[spyder]

What if in between a pattern we have to assign a single space for "anything"..how to define that in regex ??

[petramilanovic]

It was really helpful. Thank you very much!

[tonymagana]

This is interesting. Is this how programs check if our new passwords are valid, for example when they say it must be at least 8 characters long and include at least one symbol?

[mariamkonare]

thank you very much for your video it helps me a lot !
