How to URL Encode Query Strings in Python?

Encoding Query Strings in Python

URL encoding is a common technique used to convert special characters in a query string into their ASCII equivalents. This ensures that the query string can be successfully passed through a URL.

Challenge:

You have a query string that needs to be URL encoded before submission. The string is constructed as follows:

queryString = 'eventName=' + evt.fields["eventName"] + '&' + 'eventDescription=' + evt.fields["eventDescription"];

Solution:

Python 2:

import urllib

safe_string = urllib.quote_plus(queryString)

Python 3:

import urllib.parse

safe_string = urllib.parse.quote_plus(queryString)

Explanation:

The quote_plus() function takes a string as an argument and returns a new string with all special characters URL encoded. This includes characters such as spaces, ampersands, and question marks.

The resulting safe_string can now be safely passed through a URL as a query string.
