使用python仅在多个空格上拆分字符串

split 可以使用用于拆分的参数:

>>> _str='The lorry ran  into the mad man  before turning over'
>>> _str.split('  ')
['The lorry ran', 'into the mad man', 'before turning over']

从 doc

字符串拆分([sep[,最大拆分]])

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 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']).

split 采用分隔符参数。只要过去 ' ' 到它:

>>> _str='The lorry ran  into the mad man  before turning over'
>>> _str.split('  ')
['The lorry ran', 'into the mad man', 'before turning over']
>>>

给你的 split() 双空格作为自变量。

>>> _str='The lorry ran  into the mad man  before turning over'
>>> _str.split("  ")
['The lorry ran', 'into the mad man', 'before turning over']
>>> 

使用 re 模块:

>>> import re
>>> example = 'The lorry ran  into the mad man  before turning over'
>>> re.split(r'\s{2}', example)
['The lorry ran', 'into the mad man', 'before turning over']

因为,您需要在两个或多个空间上拆分,所以可以这样做。

>>> import re
>>> _str = 'The lorry ran    into the mad man    before turning over'
>>> re.split("\s{2,}", _str)
['The lorry ran', 'into the mad man', 'before turning over']
>>> _str = 'The lorry ran       into the mad man       before turning over'
>>> re.split("\s{2,}", _str)
['The lorry ran', 'into the mad man', 'before turning over']
