open python files in other drive

[akbarza]

hi
I open Python by searching python word in Windows search and then the Python is opened (python 3.11 window with dark blue color ). (Is this window called python shell?)
I save my files in D drive for example in D:\akb_py_projects .

When after >>> I write the name of a python file, for example echo.py, the below error is shown:

Error:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'echo' is not defined

how can I open python files in the above address from the above python window?
thanks
