模块文件如何接收来自列表的输入？

Question

我正在尝试设置模块，我对模块还很陌生。我在网上搜索了一下，找不到这个问题的答案！

我正在尝试使用我为 QuickSort 编写的一些代码创建一个模块，但是我不确定如何从其他文件获取输入。

我在模块中的代码是：

# An algorithm to sort a list of random numbers using QuickSort

def mainSortBody(arrayToSort, begin, end):

    compareVarI = arrayToSort[begin]
    lower = begin + 1
    upper = end

    while True:

        while lower <= upper and arrayToSort[upper] >= compareVarI:
            upper = upper - 1

        while lower <= upper and arrayToSort[lower] <= compareVarI:
            lower = lower + 1

        if lower <= upper:
            arrayToSort[lower], arrayToSort[upper] = arrayToSort[upper], arrayToSort[lower]
        else:
            break

    arrayToSort[begin], arrayToSort[upper] = arrayToSort[upper], arrayToSort[begin]

    return upper


def speedSort(arrayToSort, begin, end):
    if begin >= end:
        return

    p = mainSortBody(arrayToSort, begin, end)
    speedSort(arrayToSort, begin, p-1)
    speedSort(arrayToSort, p+1, end)

def sort(arrayToSort):
    speedSort(arrayToSort, 0, len(arrayToSort) - 1)

arrayToSort = []

sort(arrayToSort)
print(arrayToSort)

我的代码在另一个文件中

import main

array = [21,31,348,283,128,348,394,586,378,1923,1381782432,12348,13284]
main.sort(array)

输出

[]
Process finished with exit code 0

任何帮助将不胜感激，谢谢。

我假设 测试文件；您运行的文件是 test.py： test.py 应该是这样的：

from main import sort # importing the sort function from main.py

array = [21,31,348,283,128,348,394,586,378,1923,1381782432,12348,13284]
sort(array)
print(array) # printing the array as the function returns None

和main.py:

# An algorithm to sort a list of random numbers using QuickSort

def mainSortBody(arrayToSort, begin, end):

    compareVarI = arrayToSort[begin]
    lower = begin + 1
    upper = end

    while True:

        while lower <= upper and arrayToSort[upper] >= compareVarI:
            upper = upper - 1

        while lower <= upper and arrayToSort[lower] <= compareVarI:
            lower = lower + 1

        if lower <= upper:
            arrayToSort[lower], arrayToSort[upper] = arrayToSort[upper], arrayToSort[lower]
        else:
            break

    arrayToSort[begin], arrayToSort[upper] = arrayToSort[upper], arrayToSort[begin]

    return upper


def speedSort(arrayToSort, begin, end):
    if begin >= end:
        return

    p = mainSortBody(arrayToSort, begin, end)
    speedSort(arrayToSort, begin, p-1)
    speedSort(arrayToSort, p+1, end)

def sort(arrayToSort):
    speedSort(arrayToSort, 0, len(arrayToSort) - 1)

# only keep the functions in this file; so removed the redundant parts or else they would also be executed.

希望这能解决您的问题。

如果我错了请纠正我，但我相信你有点倒退了。 main.py 不应该是导入的模块，因为它应该是程序的主要部分。您在 main.py 和运行中导入您需要的内容。

您可以这样做：

quicksort.py

def mainSortBody(arrayToSort, begin, end):

    compareVarI = arrayToSort[begin]
    lower = begin + 1
    upper = end

    while True:

        while lower <= upper and arrayToSort[upper] >= compareVarI:
            upper = upper - 1

        while lower <= upper and arrayToSort[lower] <= compareVarI:
            lower = lower + 1

        if lower <= upper:
            arrayToSort[lower], arrayToSort[upper] = (
                arrayToSort[upper],
                arrayToSort[lower],
            )
        else:
            break

    arrayToSort[begin], arrayToSort[upper] = arrayToSort[upper], arrayToSort[begin]

    return upper


def speedSort(arrayToSort, begin, end):
    if begin >= end:
        return

    p = mainSortBody(arrayToSort, begin, end)
    speedSort(arrayToSort, begin, p - 1)
    speedSort(arrayToSort, p + 1, end)


def sort(arrayToSort):
    speedSort(arrayToSort, 0, len(arrayToSort) - 1)

main.py

from quicksort import sort

if __name__ == "__main__":
    array = [21, 31, 348, 283, 128, 348, 394, 586, 378, 1923, 1381782432, 12348, 13284]
    sort(array)

    print(array)
