在Python2.7中去除字符串中类似于Unicode \u2026 的字符

Question

我有一个Python2.7的字符串，像这样：

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

如何将它转换成这样：

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

你想根据什么筛选字符？你只想保留 ASCII 吗？ - root

@root，是的，我只想保留ASCII。 - Sandeep Raju Prabhakar

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!"

这就是它的打印方式。 - Burhan Khalid

你为什么写 \\ 而不是 \，使用 \ 输出的结果不是和你的代码一样吗？ - zhangxaochen

这也会去除一些字符，例如 ü, ä, ö 等，但大多数情况下这是不希望的。 - Floran Gmehlin

这对我不起作用...字符串完全相同。 - coderboi
