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!
我如何将其转换为此
This is some text that has to be cleaned! its annoying!
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!"
