要在 Python 中列出的字符串 [英] String to list in Python

问题描述

我正在尝试拆分字符串:

I'm trying to split a string:

'QH QD JC KD JS'

进入一个列表，如:

['QH', 'QD', 'JC', 'KD', 'JS']

我该怎么做?

推荐答案

>>> 'QH QD JC KD JS'.split()
['QH', 'QD', 'JC', 'KD', 'JS']

split:

返回单词列表字符串，使用 sep 作为分隔符细绳.如果给定 maxsplit，最多maxsplit 拆分完成(因此，列表最多有 maxsplit+1元素).如果 maxsplit 不是指定，则没有限制拆分的数量(所有可能的进行拆分).

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made).

如果给定了 sep，则连续分隔符没有组合在一起并被视为划定空字符串(例如，'1,,2'.split(',') 返回 ['1', '', '2']).sep 参数可能包括多个字符(例如，'1<>2<>3'.split('<>') 返回 ['1', '2', '3']).拆分空字符串使用指定的分隔符返回[''].

If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2']). The sep argument may consist of multiple characters (for example, '1<>2<>3'.split('<>') returns ['1', '2', '3']). Splitting an empty string with a specified separator returns [''].

如果 sep 没有被指定或者是 None，一个不同的分裂算法是应用:连续运行空白被视为单个分隔符，结果将包含开头或结尾没有空字符串如果字符串有前导或尾随空白.因此，分裂一个空字符串或由以下内容组成的字符串只是带有 None 分隔符的空格返回 [].

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].

例如，' 1 2 3 '.split()返回 ['1', '2', '3'] 和 ' 1 2 3 '.split(None, 1) 返回 ['1', '2 3 '].

For example, ' 1 2 3 '.split() returns ['1', '2', '3'], and ' 1 2 3 '.split(None, 1) returns ['1', '2 3 '].
