Re: [Tutor] Simple reg-ex syntax?
How I would improve this:
compile the regular expression. This is more efficient.
self.digit_extractor = re.compile('(\d+)')
then, use the findall method:
self.allNumbers = self.digit_extractor.findall(self.aString)
which will even work with multiline strings, but doesn't convert to integers.
To convert, use a list comprehension:
self.allNumbers = [int(i) for i in self.digit_extractor.findall(self.aString)]
Cheers

[Tutor] Simple reg-ex syntax?
Hello,
I have code that looks something like:
self.aString = "abc123xyz"
self.theNumber = int(re.search('(\d+)',self.aString).group())
Is there a more Pythonic way of doing this? (Both the reg-ex and the Int
coercion.) How about when I will need to extract more than one substring?
Thank you,
:)
