Question

我被我的程序困住了。基本上我必须调用一个模块并让该模块创建一个文件，其中包含我稍后在程序中引用的值。但是，该模块无法正常工作，我不知道我哪里出错了。提前致谢。这是我目前的计划。

import math
import mymath

def main():

    getData()
    summer()

def getData():
    powerfile = open("myfile.dat","w")
    fin = open("sample.dat","r")
    done = False
    while not done:
        x = int(fin.readline())
        if x < 0:
            done = True
        else:
            y = int(fin.readline())
            answer = mymath.powerval(x,y)
            answer = str(answer)+'\n'
            powerfile.write(answer)
    powerfile.close()

def summer():
    file_in = open("myfile.dat","r")
    total = 0
    count = 0
    for a in file_in:
        number = int(a)
        count += 1
        total += number
    file_in.close()
    print("The final sum was", total)   

    close = input('')

main()

我的mymath模块：

import math

def powerval(x,y):
    if x > y:
        big = x
    else:
        small = x
    if x > y:
        small = y
    else:
        big = y
    answer = pow(big, small)

Answer 1

powerval函数没有返回语句。

def powerval(x,y):
    if x > y:
        big = x
    else:
        small = x
    if x > y:
        small = y
    else:
        big = y
    answer = pow(big, small)
    return answer # <----

Python：模块将“无”值返回到创建的文件中
