Repeating input to dictionary loop

Question

"Create a dictionary whose keys are names and whose value for a key is a favorite food of the person with that name as follows: - The program should prompt for a name and favorite food and keep inputting names and favorite foods until the user enters an empty string for the name."

So far I have:

mydict=dict()
def favorite_food_name():
    name=input(str("name:"))
    food=input(str("food:"))
    mydict[name]=food       
    print(mydict)
favorite_food_name()

But I can't get the code to repeat in any kind of loop. What kind of loop would you use?

Answer 1

Use While True loop, and test value of name after its input.

By the way, some tips when coding:

• you do not need str("name:") , since "name:" is str
• if not necessary, put mydict in the function part, use return statement, do not use it as model level
• you can do more to validate the input, here I call a strip function to remove typo of input.

Here is a sample code:

def favorite_food_name():
    mydict = dict()
    while True:
        name = input("name:")
        name = name.strip()
        if name == '':
            break
        food = input("food:")
        food = food.strip()
        mydict[name] = food
    # print(mydict)
    return mydict


if __name__ == '__main__':
    mydict = favorite_food_name()
    print(mydict)
