Is it possible to display a variable received in a function?

Question

Python

Here is the function:

def player_turn():
    global turn, bank
    if turn == 1:
        deck = deck_1
        bank = bank_2[:]
    else:
        deck = deck_2
        bank = bank_1[:]
    print("Ваш ход                     выберите 4 карты")
    while len(force) < 4:
        inter = input()
        if inter not in deck:
            print("этой карты нет в вашей колоде")
        else:
            force.append(inter)
    else:
        turn *= -1

is it possible to display the bank variable outside of this function

Answer 1

def foo():
    result = 2 + 2
    return result
print(foo())

если return нет в функции, то возвращается None
