python - 在python2.7中删除字符串中的unicode \u2026之类的字符

Question

我在python2.7中有一个这样的字符串，

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

我如何将其转换为这个，

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!"
