Yep! What you're looking for is the "membership" operator. It's spelled "in":

>>> x = "apple"
>>> x_list = ["apple", "banana", "peach"]
>>>
>>> if x in x_list:
...     print("That is a fruit.")
... else:
...     print("That is not a fruit.")

That is a fruit.
>>> x = "jump"
>>> if x in x_list:
...     print("That is a fruit.")
... else:
...     print("You must be Chell.")
...
You must be Chell.
