找不到文件目录错误。请帮助。FileNotFoundError：[Errno 2] 没有这样的文件或目录：'script.py'

Question

import os

def new_directory(directory, filename):
    # Before creating a new directory, check to see if it already exists
    if os.path.isdir(directory,mode="w+") == False:
        os.mkdir(directory)

    # Create the new file inside of the new directory
    os.chdir(directory)
    with open(filename) as file:
        pass

    # Return the list of files in the new directory
    return os.listdir(directory)

print(new_directory("PythonPrograms", "script.py"))

我的代码显示此错误：

     Traceback (most recent call last):
     File "C:\Users\Toshiba\Desktop\new.py", line 16, in <module>
     print(new_directory("PythonPrograms", "script.py"))
     File "C:\Users\Toshiba\Desktop\new.py", line 14, in new_directory
      return os.listdir(directory)
   FileNotFoundError: [WinError 3] The system cannot find the path specified: 
   'PythonPrograms'
  [Finished in 0.1s]

我试过不使用 mode="w+" 然后我得到另一个错误..

Answer 1

os.listdir(directory) 从其父目录中查找目录“目录”。它没有列出 当前 目录。因此删除os.chdir(directory)这一行。

import os

def new_directory(directory, filename):
    # Before creating a new directory, check to see if it already exists
    if os.path.isdir(directory) == False:
        os.mkdir(directory)

    # Create the new file inside of the new directory
    with open(filename, mode="w+") as file:
        pass

    # Return the list of files in the new directory
    return os.listdir(directory)

print(new_directory("PythonPrograms", "script.py"))

Answer 2

您在 open 函数中缺少模式

import os

def new_directory(directory, filename):
    # Before creating a new directory, check to see if it already exists
    if os.path.isdir(directory) == False:
        os.mkdir(directory)

    # Create the new file inside of the new directory
    os.chdir(directory)
    with open(filename, mode="w+") as file:
        pass

    # Return the list of files in the new directory
    return os.listdir(directory)

print(new_directory("PythonPrograms", "script.py"))
