python - 将unicode更改为实际字符？

Question

Answer 1

You can pass the bytes to decode('unicode-escape'):

s = '\\u2605 Amazing \\u2605'

s = bytes(s, 'utf8').decode( 'unicode-escape' )

print(s)
# ★ Amazing ★

note: not sure if this is a problem in your case, but decode( 'unicode-escape' ) does not handle un-escaped, non-ascii, so something like s = '\\u2605 Ama ★ zing \\u2605' would cause problems. See issue here. A possible solution in this case is to escape the entire string and then decode:

s = s.encode('ascii','backslashreplace').decode( 'unicode-escape' )
