使用函数传递参数

Question

Is this a valid example of using functions to parameter pass and output the square of a number?

num = int(input('Enter a number: '))


def squared():
    num2 = num ** 2
    print(num2)


squared()

Answer 1

Your squared function should accept a num argument, and return the result.

Something like this:

num = int(input('Enter a number: '))

def squared(num):
    return num ** 2

print(squared(num))
