re - multiple results

I'm working on the Python Challenge (make sure to try it:
http://www.pythonchallenge.com). One of the puzzles requires the use of
regular expressions, but with multiple matches in the text. I tried to
use re.findall(), but I only go one result instead of a list of results.
print re.findall(r"my expression",tex t)

['AZBaCTR']

There should, of course, be several matches. What function should I use?
Or is it not a function issue?

Thanks,
Pingveno

Works for me. Although I usually prefer this idiom:

re_something = re.compile(r"pa ttern")
re_something.fi ndall(text)

You're doing something else wrong.

"myexpressi on" won't return "AZBaCTR" for any kind of input, so I'm not
sure what "of course" really refers to...

my guess is that you're using "*" or "+" in a situation where you don't really
need them. cf.
re.findall("\w" , "abcdef") ['a', 'b', 'c', 'd', 'e', 'f'] re.findall("\w+ ", "abcdef")

['abcdef']

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
