How to use a function output as an input of another function in Python

#Method 1: using return value inside another function

def fun1(a):
    res = a + 1
    return res


def fun2(c):
    res = c * 2
    return res


output = fun1(fun2(1))
print(output)



#Method 2: directly calling one function in the other

def function_1(n):
    v = n * n
    num = function_2(v)
    return num


def function_2(a_number):
    a_number = a_number * 2
    return a_number


print(function_1(10))
