How to check if a string is null in python

+1 vote

This question already has an answer here:

I have a value cookie that is returned from a POST call using Python.

I need to check whether the cookie value is empty or null. Thus I need a function or expression for the if condition. How can I do this in Python? For example:

if cookie == NULL if cookie == None

P.S. cookie is the variable in which the value is stored.

Try this:

if cookie and not cookie.isspace():
# the string is non-empty
else:
# the string is empty

The above takes in consideration the cases where the string is None or a sequence of white spaces.
