如何添加循环的 return 值

Question

我是 python a 的新手，我需要添加循环的 return 值。该程序应该打开一个包含 1x31x6 格式尺寸的文件，对它们进行排序并进行一些数学运算。我相当确定我一切都正确，但我不知道如何将 return 值加在一起。这是我目前的代码。

def parseAndSort(string):
    """this function reads the input file, parses the values, and sorts the ints from smallest to largest"""
    int_list = string.split('x')
    nums = [int(x) for x in int_list]
    nums.sort()
    length = nums[0]
    width = nums[1]
    height = nums[2]
    surface_area = (2 * length * width) + (2 * length * height) + (2 * width * height) + (length * width)
    tape = (2 * length) + (2 * width) + (length * width * height)
    return surface_area


def main():
    file = input('Please Input Measurement File :')
    try:
        output = open(file, "r")
    except FileNotFoundError:
        print("Error, please input a dimension file.")
    else:
        for ref in output:
            parseAndSort(ref)
        output.close()


if __name__ == "__main__":
    """ This is executed when run from the command line """
    main()

我假设你的意思是你想要运行函数所有时间的 return 值的总和。您可以保留一个运行总和，并继续向其中添加每个 return 值。

def main():
    sum = 0
    file = input('Please Input Measurement File :')
    try:
        output = open(file, "r")
    except FileNotFoundError:
        print("Error, please input a dimension file.")
    else:
        for ref in output:
            sum += parseAndSort(ref)
        output.close()
        print (sum)
