Someone please explain the sentence:

Question

from sys import argv
script, filename=argv

Answer 1

The first line import "argv" object from the module "sys" in the current namespace, so it's like we've declared a variable name "argv" and assign it an object. In this case, "argv" is the list of the command line arguments...

The second line declare two variables "script" and "filename", and assign to them the two first element of the list "argv".

So, we could deduce that the Python script which contains these lines ( say it's filename is "my_script.py" ) would be run with at least one arguments...
You mean: why one and not two? Because argv[0] is the filename of the script running. If I call my script like that:

python my_script.py argument1 argument2

We'll have in "argv":

argv[0]=="my_script.py"
argv[1]=="argument1"
argv[2]=="argument2"
