为什么我无法获得此代码的输出？

def armstrong(lower,higher):

    for num in range(lower, higher+1):
        order=len(str(num))
        sum=0
        temp = num

        while temp >0:
            digit=temp%10
            sum += digit**order
            temp//=10

        if num == temp:
            return num

lower=int(input('lower number: '))
higher=int(input('higher number: '))
armstrong(lower,higher)

代码中几乎没有逻辑错误，我已经修复了它们，并添加了注释以确切显示位置。

def armstrong(lower,higher):

    result_list = [] # define a result list
    for num in range(lower, higher+1):
        order=len(str(num))
        total = 0 # Do not use sum as it is python keyword
        temp = num

        while temp != 0: 
            digit=temp%10
            total += digit**order # change the variable name
            temp//=10

        if num == total: # Check with total instead of temp
            result_list.append(num) # append to a list instead of returning
    return result_list # return the total list after all results are collected.

lower=int(input('lower number: '))
higher=int(input('higher number: '))

output = armstrong(lower,higher) # store the output of the function

print(output)

输出：

lower number: 100
higher number: 500
[153, 370, 371, 407]
