Membership Operators
You may have noticed that
in is a keyword in Python. that's because it's a special type of operator called a membership operator, which can check if something is in another thing (like if an element is in a list). Using the not in operator, you can also check if something is not in another thing. For example:my_list = [1, 2, 3, "oh no"] if "oh no" in my_list: print("oh no is an element in my_list") else: print("oh no is not an element in my_list") if 4 not in my_list: print("4 is not an element in my_list") else: print("4 is an element in my_list")
Output of the code above
oh no is an element in my_list 4 is not an element in my_list
