我是在help(pd.read_table)中对参数delim_whitespace的用法介绍中看到的,它是这么写的:
|*
delim_whitespace : bool, default False Specifies whether or not whitespace (e.g."' '" or "' '")will be used as the sep. Equivalent to setting "**sep='\s+'"** . If this option is set to True, nothing should be passed in for the "delimiter" parameter.
*|
我搜了很久也没找到'\s+'这串字符的含义,请大神告知。【秋梨膏】
