如何在 python 中的另一个 function 中调用 function

Question

def print_money(n1, n2):
    print('hello world')
    money_sum = adds_numbers(n1, n2)
    print(money_sum)
def adds_numbers(n1,n2):
    print_money(n1,n2)

adds_numbers(2,3)

I am trying to call a function from another function, why is the result giving an infinite loop.

Answer 1

Because your print_money function is calling yet another adds_number function, which in turns call yet another print_money function, and will keep on repeating this loop forever.

Sidenote: I think what you want to do is

def adds_numbers(n1, n2):
    return n1 + n2 // Returns the sum of both numbers, as implied by the function name

Answer 2

Change add_numbers to return n1+n2, that fixes the code.

def print_money(n1, n2):
    print('hello world')
    money_sum = adds_numbers(n1, n2)
    print(money_sum)
def adds_numbers(n1,n2):
    return n1+n2

adds_numbers(2,3)
