open python files in other drive

[deanhystad]

You do not want to open Python that way. Open a shell, CMD or Powershell, change directories to where your echo.py file is located, and type "python echo.py".

I do not understand what you mean by this:

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

Do you mean that at the python prompt you just typed "echo.py"? ">>>" is the prompt from the interactive python interpreter. It is prompting you to enter a python statement. For example:

Output:
>>> sum(range(100))
4950

Or in your case:

Output:
>>> from echo import echo
>>> print(echo("echo"))
