os.getcwd() 导致 FileNotFoundError

Question

我正在尝试将数据从 csv 导入数据库 following this repository。

我运行我的 windows 桌面上的功能，并得到这个错误：

['Customer Contracts$.csv', 'Customer Demo.csv', 'Customer Engagements.csv']

FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\User\Code\DatabaseImporter/datasets/Customer Contracts$.csv'

我在他使用的视频中注意到 Mac。我认为这与错误有关。我尝试使用 .replace 清理字符串，但没有得到任何不同的结果。

我创建了一些测试代码，发现了一些有趣的东西。

import os
print(os.getcwd())
os.getcwd()

C:\Users\User\Code
'C:\Users\User\Code'

我认为这也只是问题的一半，因为最后的错误中有不同的斜线。

Answer 1

使用os.path.join而不是特定的串联

使用 shutil 移动（而不是 MV）

使用os.mkdir创建目录

在 mkdir 的错误处理中指定 FileExistsError

os.getcwd() 导致 FileNotFoundError

os.getcwd() leading to FileNotFoundError

python

windows

getcwd

jupyter
