在另一个中调用 function

Question

I'm learning to code and am trying to learn to use functions more and more. I have 3 different functions here, and I haven't progressed far with the user_menu() function as I get stuck with the last piece of code in the if statement/construction.

The times_table() function keeps repeating itself no matter what I do or what code I add. It stays on that last line of the if statement in the user_menu() function. What can I do to remedy this?

I would also like to add the times_table2() function to the user_menu() function just under the times_table() function.

I would also like to ask for recommendations on how to combine the two times_table() functions into a single function whilst keeping the functionality. I haven't come across an example online or in the book and it's quite frustrating to be very honest.

I would appreciate some info and possibly some websites for more resources.

Regards and thanks in advance.

def user_menu():
    options = ["1. Would you like to learn to multiply two numbers of your choice?",
               "2. Would you like to learn to multiply a number in a table?"]
    print(*options, sep="\n")

    user_input = int(input("Please select from the list above: "))
    if user_input == 1:
        times_table(multiple="Please enter the number you wish to learn to multiply with")





def times_table(multiple):
    while True:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
        except ValueError:
            print("Please enter a numerical value!")
            continue
            return multiple_int
def times_table2(multiple):
    while True:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
        except ValueError:
            print("Please enter a numerical value!")
            continue
            return multiple_int

You should use return after you get correct value

def times_table(multiple):
    while True:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
            return multiple_int
        except ValueError:
            print("Please enter a numerical value!")

Eventually use break to exist while loop and then use return

def times_table(multiple):
    while True:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
            break # exit loop
        except ValueError:
            print("Please enter a numerical value!")

    # after `while` loop
    return multiple_int

EDIT: As I said in comment you can do it in different way. If you really need to use continue then do as @Kevin suggested

def times_table(multiple):
    while True:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
        except ValueError:
            print("Please enter a numerical value!")
            continue

        # inside `while` but not in `except`
        return multiple_int

In second version you can also use variable True/False instead of break

def times_table(multiple):
    repeat = True
    while repeat:
        multiple_text = input(multiple)
        try:
            multiple_int = int(multiple_text)
            repeat = False # exit loop
        except ValueError:
            print("Please enter a numerical value!")

    # after `while` loop
    return multiple_int
