How to check if the string is empty?

Question

Does Python have something like an empty string variable where you can do:

if myString == string.empty:

Regardless, what\'s the most elegan

Answer 1

I find this elegant as it makes sure it is a string and checks its length:

def empty(mystring):
    assert isinstance(mystring, str)
    if len(mystring) == 0:
        return True
    else:
        return False
