Python chmod，权限问题答案

【问题描述】：

我只是遇到了 chmod 方法的问题。我并不完全了解编程，但我有一些经验，我正在尝试编写一个脚本来跟踪我的小型家庭企业的收入和支出。

我认为问题在于写入文件的部分或 chmod 方法，两者都靠近底部：

weeklyDatetime = datetime.now()
weeklyDate = weeklyDatetime.strftime("%Y, %m, %V - Incomes")

incomeFileNameAndDirectory = incomesPath + "\\" + weeklyDate + ".txt"
weeklyIncomeFile= open(incomeFileNameAndDirectory, "w+")
weeklyIncomeFile.close()

makingChoice = True
while makingChoice == True:
    print("1. Add another Income\n"
          "2. Stop adding incomes")
    
    addIncomeOrNo = input()

    if addIncomeOrNo == "1":
       print("Please enter the name of this income: ")
        incomeName = input()
        print("Please enter the amount of this income: ")
        incomeAmount = input()
        print("Please enter any additional descriptions for this income: ")
        incomeDescription = input()
        print("Thank you.\n")

        with open(incomesPath, "a") as weeklyIncomeFile:
            os.chmod(incomeFileNameAndDirectory, stat.S_IRWXO)
            weeklyIncomeFile.write("\n" + incomeName + "\t\t" + incomeAmount + "\t\t" + incomeDescription)

我想我可能没有正确使用 os.chmod 方法？我仍然收到以下错误：

PermissionError: [Errno 13] Permission denied: 'C:\Users\iarko\Desktop\PCE Business\Financials\Incomes'

请告诉我问题是什么，感谢您的阅读！

【解决方案1】：

主要问题在于您的with open(incomesPath, "a") as weeklyIncomeFile: 行，您尝试在其中打开一个像文件一样的目录。

在 Python 3 中，我建议使用：

pathlib 用于路径
f-strings 用于在字符串中打印值

而且变量名通常是小写的。

考虑到这些修改，您的代码可能如下所示：

from datetime import datetime
from pathlib import Path
from subprocess import check_output

weekly_datetime = datetime.now()
weekly_date = weekly_datetime.strftime("%Y, %m, %V - Incomes")

incomes_path = Path("C:\\Users\\iarko\\Desktop\\PCE Business\\Financials\\Incomes")

income_file_path = incomes_path / f"{weekly_date}.txt"
income_file_path.touch()
# If you need to set the correct access rights, use "icacls in Windows"
check_output(
    ["icacls", str(income_file_path), "/inheritance:r", "/grant:r", f"Everyone:F"]
)

making_choice = True
while making_choice == True:
    print("1. Add another Income\n2. Stop adding incomes")
    add_or_stop = input()

    if add_or_stop == "2":
        making_choice = False

    if add_or_stop == "1":
        print("Please enter the name of this income: ")
        name = input()
        print("Please enter the amount of this income: ")
        amount = input()
        print("Please enter any additional descriptions for this income: ")
        description = input()
        print("Thank you.\n")

        with open(income_file_path, "a") as f_income:
            f_income.write(f"\n{name}\t\t{amount}\t\t{description}")
