如何截取字符串？

[ioiioi]

假设有一个tuple为[['128 MB', '27 PERCENT']]
我想将128和27全部转换成int，该怎么截取字符串？

[mrluanma]

>>> [int(x.split(None, 1)[0]) for x in ['128 MB', '27 PERCENT']]
[128, 27]

有个疑问，split(None, 1)是啥意思？

@ioiioi

>>> help("".split)

Help on built-in function split:

split(...)
S.split([sep [,maxsplit]]) -> list of strings

Return a list of the words in the string S, using sep as the
delimiter string. If maxsplit is given, at most maxsplit
splits are done. If sep is not specified or is None, any
whitespace string is a separator and empty strings are removed
from the result.

import re

[map(int, re.findall(r'\d+', x)) for x in ['128 MB', '27 PERCENT']]
