Access a file even if the cwd has changed

Question

The below code works perfectly:

with open('data.txt') as data:
    print(data)

But if I changed the CWD using os.chdir, It won't work

Is there a way in which I can access the file while still being able to change the CWD?

Note: The way the CWD will change will depend on how the user uses it.

Answer 1

thank you for your answers

But I think I have got it myself!

Before I call the os.chdir function, I can do,

from pathlib import Path
datafile = Path('data.txt').absolute()

Then I will get the absolute path in any computer that I run this in.
