How Do I URL Encode Query Strings in Python?

URL Encoding Query Strings in Python

When submitting forms online, it's essential to URL encode query strings to prevent special characters from breaking the transmission.

For instance, consider creating a string representing form data:

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

To securely submit this string, you need to URL encode it.

Python 2

Python 2 offers the urllib.quote_plus function:

import urllib
safe_string = urllib.quote_plus(queryString)

Python 3

In Python 3, use urllib.parse.quote_plus from the parse child package:

import urllib.parse
safe_string = urllib.parse.quote_plus(queryString)

This will transform special characters into their URL-safe counterparts, ensuring the string is correctly transmitted.
