In Python, a string is a sequence (like an array); therefore, the in operator can be used to check for the existence of a character in a Python string. The in operator is used to assert membership in a sequence such as strings, lists, and tuples.

cool = "Sam!"
'!' in cool # True

Alternately you can use any of the following for more information:

cool.find("!") # Returns index of "!" which is 3
cool.index("!") # Same as find() but throws exception if not found
cool.count("!") # Returns number of instances of "!" in cool which is 1

Use the following

cool="Sam!"
if "!" in cool:
    pass # your code

Or just: 

It_Is="!" in cool
# some code
if It_Is:
    DoSmth()
else:
    DoNotDoSmth()

Use the in operator

>>> cool = "Sam!"
>>> '!' in cool
True
>>> '?' in cool
False

As you can see '!' in cool returns a boolean and can be used further in your code
