Python strip() Unicode 字符串? [英] Python strip() unicode string?

问题描述

如何在 unicode 字符串上使用像 strip() 这样的字符串方法?并且您不能像普通字符串一样访问 unicode 字符串的字符吗?(例如: mystring[0:4] )

解决方案

它照常工作，只要它们实际上是 unicode，而不是 str(注意:每个字符串文字必须前面有u，就像这个例子一样):

<预><代码>>>>a = u"coțofană">>>一种你'co\u021bofan\u0103'>>>[-1]你'\u0103'>>>a2]你'\u021b'>>>[3]你哦>>>a.strip(u'ă')u'co\u021bofan'

How can you use string methods like strip() on a unicode string? and can't you access characters of a unicode string like with oridnary strings? (ex: mystring[0:4] )

解决方案

It's working as usual, as long as they are actually unicode, not str (note: every string literal must be preceded by u, like in this example):

>>> a = u"coțofană"
>>> a
u'co\u021bofan\u0103'
>>> a[-1]
u'\u0103'
>>> a[2]
u'\u021b'
>>> a[3]
u'o'
>>> a.strip(u'ă')
u'co\u021bofan'
