How to receive two passed cmdline parameters and access them inside a Python script?

[pstein]

Sorry for this newbie question:

Assume I have have a python script myscript.py (on Windows 10).

Now I want to call this script (from command line) and pass two parameters (separrted by blanks) e.g.

myscript.py "D:\tools\input data.txt" 65656

The parameters may or may not enclosed in double quotes (as above).

How can I access these passed parameters from inside the script?
Say I want to echo/output them (=the values) simply on command line.

It would be nice to get a sample script.

Thank you
Peter
