Python 无效的目录名

我收到错误信息：

File "C:/Users/AM/PycharmProjects/booyah/first.py", line 5, in main
directory = os.chdir(input('Enter the directory of the file you want to read'))
NotADirectoryError: [WinError 267] The directory name is invalid: 'C:\\Users\\AM\\Desktop\\Sad.txt'

这是我的密码：

import os

def main():
    answer = input('Would you like to read, write, create, or quit?')
    if(answer == 'read'):
        directory = os.chdir(input('Enter the directory of the file you want to read'))
        w = open(directory, 'r')
        contents = w.read()
        print(contents)
        w.close()

我复制到的目录指向我桌面上的一个文本文件。

谢谢你的帮助

关于您想要在这里实现什么，有点模棱两可，但下面是一个快速示例，说明如何将

read

命令

chdir

解析到指定的目录中，并打印出文件的行

我在本例中硬编码了文件名：

import os

answer = input('Would you like to read, write, create, or quit?: ')
file_name = 'Sad.txt'

if(answer == 'read'):
    directory = os.chdir(input('Enter the directory of the file you want to read: '))

    with open(file_name, 'r') as fh:
        for line in fh.readlines():
            print(line)

…下面是一个非常简短的示例，显示了如果您希望用户发送包含该文件的路径，则如何读取该文件：

import os

answer = input('Would you like to read, write, create, or quit?: ')

if(answer == 'read'):
    file_name = input('Enter the file you want to read: ')

    with open(file_name, 'r') as fh:
        for line in fh.readlines():
            print(line)

代码抛出一个“NotADirectoryError”，您的输入以“Sad.txt”结尾。。。我不认为目录以.txt结尾？一个

目录

并不等于一个

路径

。你提供的是后者。如果需要文件的目录，请调用

os.path.dirname（file\u变量）

。
