如何编码/解码 Python 中的百分比编码 (URL) 字符串？

Question

How do I decode percent-encoded characters to ordinary unicode characters?

 "Lech_Kaczy%C5%84ski" ⟶ "Lech_Kaczyński"

Answer 1

For Python 3, using urllib.parse.unquote :

 from urllib.parse import unquote print(unquote("Lech_Kaczy%C5%84ski"))

Output:

 Lech_Kaczyński

Answer 2

For Python 2, using urllib.unquote:

import urllib
urllib.unquote("Lech_Kaczy%C5%84ski").decode('utf8')

This will return a unicode string:

u'Lech_Kaczy\u0144ski'

which you can then print and process as usual. For example:

print(urllib.unquote("Lech_Kaczy%C5%84ski").decode('utf8'))

will result in

Lech_Kaczyński

Answer 3

This worked for me:

 import urllib print urllib.unquote('Lech_Kaczy%C5%84ski')

Prints out

Lech_Kaczyński
