Question

def FilmSelection():
    list1=["The Magnificent Seven",'Wreck It Ralph','James Bond','Now you see me 2','Captain America:The Winter Soldier']
    choice=input("what film would you like to watch?")
    while choice!=str(list1[1:5]):
        print("sorry, that film is not available right now")
        choiceb=input("would you like to select a different film?")
        if choiceb=="yes"or choiceb=="Yes":
            print("that's fine")
            choice=input("what film would you like to watch?")
        else:
            print("have a nice day")
            sys.exit()
    else:
        print("lets get to times!")

Answer 1

当用户输入其中一个电影名称时，您的while条件将不匹配。相反，使用这个:

while choice not in list1:

这将发现如果choice是in list1。此外，您应该这样做，而不是使用else:

while choice not in list1:
    # ...
print('Let’s go to times!')
