Python:将unicode字符转换为对应的Unicode字符串

Question

如何在 Python 中将 unicode 字符 'ב' 转换为对应的 Unicode 字符串 '\u05d1'？

我前几天问了相反的问题: Python: convert unicode string to corresponding Unicode character

Answer 1

你可以这样做，

>>> x
'ב'
>>> x.encode('ascii', 'backslashreplace').decode('utf-8')
'\\u05d1'

来自docs :

The errors parameter is the same as the parameter of the decode()method but supports a few more possible handlers. As well as 'strict','ignore', and 'replace' (which in this case inserts a question markinstead of the unencodable character), there is also'xmlcharrefreplace' (inserts an XML character reference),backslashreplace (inserts a \uNNNN escape sequence) and namereplace(inserts a \N{...} escape sequence).
