Why is the current directory misaligned between the .py and .ipynb files?

In order to move directories and save csv data, I have tried and tried many things with ipynb files.
I was able to confirm that ipynb works fine, so I ran a full copy of the code into the py file and got an error saying that the directory was not found.
So when I checked the current directory of ipynb and py (sample.ipynb, sample.py), I found that it was one tier off.

The code you executed for directory verification is as follows:

importos
print(os.getcwd())
os.chdir('../')
print(os.getcwd())

The results are as follows:

sample.ipynb

 d:\Data\XXX\Python
d:\Data\XXX

sample.py

D:\Data\XXX
D:\Data

It is true that the directories for both files are in the same hierarchy (see below).

D:
- - Data
   XXXX
      Yes - Python
         --sample.ipynb
         -- sample.py

As for execution, it works just by changing "..." to "." when moving, but I can't help but worry that the directory is out of alignment even though it is in the same hierarchy.
Why does this happen?

Both were done in VSCode.

The settings.json are as follows.
