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

问题描述

我正在尝试分割字符串:

I'm trying to split a string:

'QH QD JC KD JS'

进入类似列表:

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

我将如何去做?

推荐答案

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

split :

返回列表中的单词 字符串，使用sep作为分隔符 细绳.如果给出maxsplit，则最多为 maxsplit拆分已完成(因此， 列表最多包含maxsplit+1 元素).如果maxsplit不是 指定，则没有限制 分割数(所有可能 进行了分割.)

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).

如果给出sep，则连续 分隔符未组合在一起 并被视为分隔空 字符串(例如， '1,,2'.split(',')返回['1', '', '2']). sep参数可以包括 多个字符(例如， '1<>2<>3'.split('<>')返回['1', '2', '3']).分割空字串 具有指定的分隔符的返回 [''].

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 [''].

如果未指定sep或None，则a 不同的分割算法是 已应用:连续运行 空格被视为单个 分隔符，结果将包含 开始或结尾没有空字符串 如果字符串开头或结尾 空格.因此，将 空字符串或包含以下内容的字符串 仅带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']，' 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 '].
