python - 更改代码后权限被拒绝

问题描述

我还是个新手，如果我搞砸了，很抱歉：D

因此，我正在尝试编写一个脚本，该脚本通过一些 .xml 文件来获取某些行并将它们放入 Excel 工作表中。

代码：

import os
import openpyxl


def main():
    print_header()
    folder = get_folder_from_user()
    if not folder:
        print("Sorry, that folder doesn't exist.")
        return

    text = get_search_text_from_user()
    if not text:
        print("Sorry, I can't search for nothing.")
        return
    count = input("Show match count? y/n")
    name = "output.xlsx"
    # name = input("Name for workbook: ")

    x = []
    output = search_file(folder, text)
    match_count = 0
    for i in output:
        match_count += 1
        string = i
        string = string.split(">")
        string = string[1]
        string = string.split("<")
        string = string[0]
        i = string
        print(i)
        x.extend([i])
    write_to_workbook(name, x)

    if count == "y":
        print("==================")
        print("Found {} matches".format(match_count))
        print("==================")


def write_to_workbook(name, x):
    wb = openpyxl.Workbook()
    ws = wb.active
    a = 1
    ws.append(x)
    wb.save("C:/Users/Kevin/Desktop/{}".format(name))
    a += 1


def print_header():
    print("-----------------------------------")
    print("----------File Search App----------")
    print("-----------------------------------")
    print()


def get_folder_from_user():
    folder = input("Which folder do you want to search? ")
    if not folder or not folder.strip():
        return None

    if not os.path.isdir(folder):
        return None

    return os.path.abspath(folder)


def get_search_text_from_user():
    print("Which data do you want me to copy for you?")
    print("[1]SeqTest Read")
    print("[2]SeqTest Write")
    print("[3]Random 4K1TTest Read")
    print("[4]Random 4K1TTest Write")
    print("[5]Random 4K64TTest Read")
    print("[6]Random 4K64TTest Write")
    print("[7]AccTimeTest Read")
    print("[8]AccTimeTest Write")
    print("[9]Score")
    print("[0]All")
    choice = int(input("Choose now: "))

    if choice == 1:
        line = 15
    elif choice == 2:
        line = 16
    elif choice == 3:
        line = 19
    elif choice == 4:
        line = 20
    elif choice == 5:
        line = 23
    elif choice == 6:
        line = 24
    elif choice == 7:
        line = 27
    elif choice == 8:
        line = 28
    elif choice == 9:
        line = 99
    elif choice == 0:
        line = 100
    else:
        line = 0
    line = 15
    return int(line)


def search_folders(folder, line):
    items = os.listdir(folder)

    for item in items:
        full_item = os.path.join(folder, item)
        if os.path.isdir(full_item):
            yield from search_folders(full_item, line)
        else:
            yield from search_file(full_item, line)


def search_file(filename, line):
    with open(filename, 'r', encoding='utf-8') as fin:

        lines = fin.readlines()

    if line == 99:
        print(lines[31])
        print(lines[32])
        print(lines[33])
        yield ("/n".join(lines[31:34]))
    elif line == 100:
        s = 0
        while s < 10:

            print(filename)
            print(lines[4])
            if line == 15 or 16:
                print("Seq")
                if line == 15:
                    print("Read")
                else:
                    print("Write")
            elif line == 19 or 20:
                print("4k ")
                if line == 19:
                    print("Read")
                else:
                    print("Write")
            elif line == 23 or 24:
                print("4k 64")
                if line == 23:
                    print("Read")
                else:
                    print("Write")
            elif line == 27 or 28:
                print("Acc")
                if line == 27:
                    print("Read")
                else:
                    print("Write")
            elif line == 99:
                print("")
            yield (lines[line])
    else:
        print(filename)
        print(lines[4])
        if line == 15 or 16:
            print("Seq")
            if line == 15:
                print("Read")
            else:
                print("Write")
        elif line == 19 or 20:
            print("4k ")
            if line == 19:
                print("Read")
            else:
                print("Write")
        elif line == 23 or 24:
            print("4k 64")
            if line == 23:
                print("Read")
            else:
                print("Write")
        elif line == 27 or 28:
            print("Acc")
            if line == 27:
                print("Read")
            else:
                print("Write")
        elif line == 99:
            print("")
        yield (lines[line])


if __name__ == '__main__':
    main()

简而言之：用户必须输入包含文本文件的目录。然后选择想要的线路。（固定到第 15 行进行测试。当我想要在选择中指定每一行时，我没有解决问题）。然后询问用户他是否想要匹配的总数。然后它遍历所有文本文件并输出每个文件的第 15 行（只是来自 ssd 基准测试的一些数据）。数据被写入一个excel文件。代码大部分都在工作。我仍然需要弄清楚如何正确地将数据输出到excel（格式不是我想要的）。但问题是，一旦我添加此代码，目录的权限就会改变：

def trigger_search(filename, line):
    xyz = search_file(filename, line)
    return xyz

一旦我添加了这个，我就会得到一个 errno 13: Permission denied。它不能再访问带有 .xml 文件的目录。即使我删除添加的代码，我仍然会收到此错误。唯一的解决方法是复制“未更改”代码（没有 trigger_search）并覆盖 .py 文件。只需复制粘贴，它就可以正常工作（无论我多久运行一次代码）。

任何提示为什么会发生这种情况以及如何解决这个问题？

请不要因为代码太苛刻，我知道这真的很像新手。它会在它工作后立即正确制作：D
