How to Decode URL-Encoded UTF-8 Strings in Python?

Decoding URL-Encoded UTF-8 Strings in Python

When working with URLs, you may encounter strings that have been encoded using UTF-8 and escaped with URL quoting. To extract the correct data from these strings, you need to decode them.

In Python 2.7, you can use urllib.unquote() to decode URL-encoded data. However, this method returns bytes, so you need to decode them further:

<code class="python">from urllib import unquote

url = unquote(url).decode('utf8')</code>

In Python 3 and above, the urllib package has been split into urllib.request, urllib.parse, and urllib.error. To decode URL-encoded data, you should use urllib.parse.unquote():

<code class="python">from urllib.parse import unquote

url = unquote(url)</code>

This method handles both URL encoding and UTF-8 decoding, giving you a unicode string as the result.

For example:

<code class="python">>>> from urllib.parse import unquote
>>> url = 'example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0'
>>> unquote(url)
'example.com?title=правовая+защита'</code>

By using urllib.parse.unquote(), you can easily decode URL-encoded UTF-8 strings, ensuring that you obtain the correct data.
