python - os.path.abspath('file1.txt') doesn't return the correct path

Question

Say the path of the file 'file1.txt' is /home/bentley4/Desktop/sc/file1.txt Say my current working directory is /home/bentley4

import os
os.path.abspath('file1.txt')

returns /home/bentley4/file1.txt

os.path.exists('file1.txt')

returns False. If I do

os.path.abspath('file_that_does_not_exist.txt')

It returns /home/bentley4/file_that_does_not_exist.txt But again, this is not correct. The file does not even exist on my computer. Is there a way to get the correct absolute path from any directory I am currently working in? (aside from defining a new function)

So this only works when I am in the same directory as the existing file or in the directory one directory or more further from the path of the directory of that file?

Answer 1

os.path.abspath(filename) returns an absolute path as seen from your current working directory. It does no checking whether the file actually exists.

If you want the absolute path of /home/bentley4/Desktop/sc/file1.txt and you are in /home/bentley4 you will have to use os.path.abspath("Desktop/sc/file1.txt").
