add user input to list

I want it to ask the user to input their favorite film and it to add that input at the end of the list and then display the list again. as well as making sure the film entered is not in the least already. this is how far ive got up to :

films = ["Star Wars", "Lord of the Rings", "Shawshank Redemption", "God father"]

for films in films:
    print ("%s" % films)

add = input("Please enter a film: ")
films.insert(-1,add)
print (films)

Edit:

When I tried that I get an error:

Traceback (most recent call last):

File "H:\Modules (Year 2)\Advanced programming\Python\Week 2 - Review and Arrays\Week 2.2 - Exercises.py", line 48, in films.append(add) AttributeError: 'str' object has no attribute 'append'

"""
This is for a dictionary
""""
Cities={"London":0,"Cairo":2182,"Lagos":3110,"Lima":6314}
while True:
    city=input("Enter a city")
    if city in Cities:
        print (Cities[city])
    else:
        print("Not in dictionary please input the distance")
        distance=input()
        Cities[city]=int(distance)
        print (Cities)

The error is here:

for films in films:
    print("%s" % films)

You are doing for films in films instead of for film in films.

Also, the others are correct that a better way of writing films.insert(-1, ...) is films.append(...).

Check if it is already in list with not in and use append to add it to the end of the list:

films = ["Star Wars", "Lord of the Rings", "Shawshank Redemption", "God father"]

for films in films:
    print ("%s" % films)

add = input("Please enter a film: ")
if add not in films: films.append(add)
else: print("Already in list!")
print (films)

Use in to check whether the item is already present in list or not and then use list.append to add that item to the end of the list.

add = input("Please enter a film: ")
if add not in films:
    films.append(add)

Note that in the for-loop you've replaced films with a string, use some other variable name:

for film in films:
    print ("%s" % film)
