Import python file into another python file

Question

Before this is marked as duplicate please read the full problem.

So I have a folder structure like this:

main.py
|
|_one
 |_ one.py
 |_ file.txt 

What i'm doing is, importing one.py into main.py and calling a function. My py files are,

main.py

import one 
one.f1('test')

one.py

def f1(param):
 with open("file.txt", "r") as f:
 print(f+param)

When I run main.py, I keep getting this error : FileNotFoundError: [Errno 2] No such file or directory: 'file.txt'.

I have also tries os.path.abspath() but still no luck. Am I doing something wrong?

Thank you!

The path is computed from the root directory not the directory the the calling code resides in. Try one/file.txt for Linux environment.

• Sab: Post the code , stacktrace and related resources, then the community can help.
• ShadowRanger: @hrishikeshpaul: That's an entirely unrelated error, in code you haven't posted. You're welcome to ask a new question with a minimal reproducible example, but asking new questions in comments on the answer to your actual question is frowned upon.
• ShadowRanger: Note: I'd suggest not using one/file.txt since that'll only work if your working directory is the same as main.py's. os.path.join(os.path.dirname(__file__), 'file.txt') (from within one.py) will find the data file relative to the source file, which works regardless of your working directory.
