Python Return a Variable in the file-CodePudding

I have tuple variables which are France, Germany. I'm trying to give a value to my bring_cities function and if it's France or Germany, I like to see the France and Germany tuple objects. Is there any shortcut to not use if loops like I did in the below ?

France = (
    ('Paris', 'Paris'),
    ('Lyon', 'Lyon'),
)
Germany = (
    ('Frankfurt', 'Frankfurt'),
    ('Berlin', 'Berlin'),
)

cities = (('', ''),)   France   Germany

def bring_cities(country): 
    if country == 'France':
        return France
    if country == 'Germany':
        return Germany
    ...

CodePudding user response：

You can create a dictionary so you don't have to write an if statement for each country. You can use the following code for that.

France = (
    ('Paris', 'Paris'),
    ('Lyon', 'Lyon'),
)
Germany = (
    ('Frankfurt', 'Frankfurt'),
    ('Berlin', 'Berlin'),
)

dictionary = {"France": France, "Germany": Germany}


def bring_cities(country):
    return dictionary[country]

to make it even shorter you can define your Countries inside the dictionary.

dictionary = {
              "France": (('Paris', 'Paris'), ('Lyon', 'Lyon')),
              "Germany": (('Frankfurt', 'Frankfurt'), ('Berlin', 'Berlin'),)
              }

France = (

Germany = (
    ('Frankfurt', 'Frankfurt'),
    ('Berlin', 'Berlin'),
)

dictionary = {"France": France, "Germany": Germany}


def bring_cities(country):
    print(dictionary[country])
    
user_choice = input("Enter a Country (France/Germany) and we will give you Cities in it: ")
bring_cities(user_choice)
