Q.2 I couldn't get line 3. module name is available as global var but from where we are accessing this ?in same/different file ?

Question

A module is a file containing Python definitions and statements.

The file name is the module name with the suffix
.py appended.

Within a module, the module’s name (as a string) is available as the value of the global variable __name__.

Answer 1

from inside the module file source, there's a global variable named __name__ wich contains the string name of the file...

as in running script (executed by user), global __name__ == "__main__"
