删除python2.7中字符串中的unicode\u2012字符

Question

我在python2.7中有一个像这样的字符串,

 This is some \u03c0 text that has to be cleaned\u2026! it\u0027s annoying!

我怎么把它转换成这个,

This is some text that has to be cleaned! its annoying!

Answer 1

Python 2.x

>>> s
'This is some \\u03c0 text that has to be cleaned\\u2026! it\\u0027s annoying!'
>>> print(s.decode('unicode_escape').encode('ascii','ignore'))
This is some  text that has to be cleaned! it's annoying!

Python 3.x

>>> s = 'This is some \u03c0 text that has to be cleaned\u2026! it\u0027s annoying!'
>>> s.encode('ascii', 'ignore')
b"This is some  text that has to be cleaned! it's annoying!"
