我有一个大文件,我需要从中加载到一个字符串列表中。每个元素都将包含文本,直到紧跟在数字后面的“,”
例如:
this is some text, value 45789, followed by, 1245, and more text 78965, more random text 5252,
这应该变成:
["this is some text, value 45789", "followed by, 1245", "and more text 78965", "more random text 5252"]
我目前正在做re.sub(r'([0-9]+),','~', <input-string>)然后在“~”上拆分(因为我的文件不包含 ~)但这会抛出逗号前的数字。有什么想法吗?
请您参考如下方法:
您可以使用 re.split与 positive look-behind assertion :
>>> import re
>>>
>>> text = 'this is some text, value 45789, followed by, 1245, and more text 78965, more random text 5252,'
>>> re.split(r'(?<=\d),', text)
['this is some text, value 45789',
' followed by, 1245',
' and more text 78965',
' more random text 5252',
'']
