Python: Importing urllib.quote

urllib went through some changes in Python3 and can now be imported from the parse submodule

>>> from urllib.parse import quote  
>>> quote('"')                      
'%22'

In Python 3.x, you need to import urllib.parse.quote:

>>> import urllib.parse
>>> urllib.parse.quote("châteu", safe='')
'ch%C3%A2teu'

According to Python 2.x urllib module documentation:

NOTE

The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.

If you need to handle both Python 2.x and 3.x you can catch the exception and load the alternative.

try:
    from urllib import quote  # Python 2.X
except ImportError:
    from urllib.parse import quote  # Python 3+

You could also use the python compatibility wrapper six to handle this.

from six.moves.urllib.parse import quote

This is how I handle this, without using exceptions.

import sys
if sys.version_info.major > 2:  # Python 3 or later
    from urllib.parse import quote
else:  # Python 2
    from urllib import quote
