将字符串拆分为列表，且列表项的长度相等 [英] Split string into a list, with items of equal length

问题描述

我有一个字符串(无空格)，我需要将其拆分为长度相等的项目列表.我知道split()方法，但是据我所知，它仅通过空格而不是长度进行分割.

I have a string (without spaces) which I need to split into a list with items of equal length. I'm aware of the split() method, but as far as I'm aware this only splits via spaces and not via length.

我想做的是这样的:

string = "abcdefghijklmnopqrstuvwx"
string = string.Split(0 - 3)
print(string)

>>> ["abcd", "efgh", "ijkl", "mnop", "qrst", "uvwx"]

我曾考虑过遍历列表，但我想知道是否有一个更简单的解决方案?

I have thought about looping through the list but I was wondering if there was a simpler solution?

推荐答案

>>> [string[start:start+4] for start in xrange(0, len(string), 4)]
['abcd', 'efgh', 'ijkl', 'mnop', 'qrst', 'uvwx']

即使最后一块少于4个字符，它也可以工作.

It works even if the last piece has less than 4 characters.
