2 months agoThanks for sharing this. I took the time to read through the documentation of the re module. Here’s my review of the functions.
Useful:
re.finditerreturns an iterator over all Match objectsre.searchreturns the first Match object or None if there are no matches.r''use raw strings for patters so you don’t have to worry about backslashes- the optional
flagsargument modifies the behaviour (case insensitive, multiline)
Utility:
re.subreplace each match in the stringre.splitsplit a string by a regular expression
The Match object:
match.groups(0)returns the portion of text matched by the patternmatch.groups(1)returns the first capturing groupmatch.groups(2)returns the second capturing group, and so on
I don’t understand why these exist:
re.matchlike search, but only matches at the beginning of the string. why not just use ‘^’ or ‘\A’ in the pattern you pass to ‘search’?re.fullmatchlike ‘search’, but only if the full string matches. Why not just use ‘\A’ and ‘\Z’ in the pattern you pass to ‘search’?re.findallReturns all matches. It seems like a shitty version of ‘finditer’. The function has three different return types which depend on the pattern you pattern you pass to the function. Who wants to work with that?
Thank you for the very thorough reply! This is kind of high quality stuff you love to see on Lemmy. Your use cases seem very valid.
