File/Folder Structure when running Python ?

Hello.

A quick question on running Python code and how 'code runner' uses directories:

I have a following folder structure:


Then I reference the .txt file in week_1.py like this:

`fruits = pd.read_csv('materials/fruit_data_with_colors.txt', sep='\t')`

And it fails as the file is not found if I use 'code runner' from VS.
If I run this in terminal, it finds the file and executes correctly.

For VSCode/Code Runner I have to use strange structure like this to make it work:


And then reference the file like this:
`fruits = pd.read_csv('fruit_data_with_colors.txt', sep='\t')`
It works, even though that .txt file is not local to .py file

How can I make it understand where I am running my code from and pick up local files/folders accordingly?
