按长度将字符串拆分为字符串? [英] Split string into strings by length?

问题描述

有没有办法取一个4*x个字符长的字符串，把它剪成4个字符串，每个x个字符长，不知道长度字符串?

Is there a way to take a string that is 4*x characters long, and cut it into 4 strings, each x characters long, without knowing the length of the string?

例如:

>>>x = "qwertyui"
>>>split(x, one, two, three, four)
>>>two
'er'

推荐答案

>>> x = "qwertyui"
>>> chunks, chunk_size = len(x), len(x)/4
>>> [ x[i:i+chunk_size] for i in range(0, chunks, chunk_size) ]
['qw', 'er', 'ty', 'ui']
