从文件夹读取 file.txt 到其他文件夹会出错

Question

Hello Guys this is my project tree:

C:.
├───data
│   └───path
│           name.txt
│
└───Resources
        get.py

I need to read text from name.txt file.

I add this code in get.py :

class path():

    with open('data/path/name.txt', 'r') as file:
        path = file.readline()
        print(path)

this not working I see this message error:

Traceback (most recent call last):
  File "C:\Users\JOHN\Desktop\New folder\Resources\get.py", line 1, in <module>
    class path():
  File "C:\Users\JOHN\Desktop\New folder\Resources\get.py", line 3, in path
    with open('data/path/name.txt', 'r') as file:
FileNotFoundError: [Errno 2] No such file or directory: 'data/path/name.txt'

Answer 1

If you start the filepath with a name, it will continue from the working directory (the directory of the python file if you're running in IDLE).

If you want to specify an absolute path on windows, add C:/ to the beginning, so with your example:

open('C:/data/path/name.txt', 'r')

Answer 2

Try with the full path C:/data/path/name.txt or relative ../data/path/name.txt .

Answer 3

To use a relative path (as you're doing now), you need to modify your relative path so that it begins one level up. Try this:

open('../data/path/name.txt', 'r')
