Does Python have a string 'contains' substring method?

Yes, Python has a string method called str.__contains__() that allows you to check if a string contains another string. You can also use the in keyword to check if a string contains another string. Note: The in operator is the recommended, Pythonic way to check for substrings.

Here is an example of how to use the str.__contains__() method:
