Collins Congratulations for your first step into Python Programming.
You can call them script or programs(not necessarily but depends on what your
coding for).
Yaa..it's always a good practice to call it through main(), but it doesn't
really matter you
can call the method in way....

Subject: Total newbie question: Best practice
Hi,
I am just starting to learn Python (I have been at it only a few hours),
so please bear with me. I have a few very small scripts (do you call them
scripts or programs?) which work properly, and produce the results
intended.
However, they are monolithic in nature; i.e. they begin at the beginning
and finish at the end. Having done a little reading, I note that it seems
to be quite common to have a function main() at the start (which in turn
calls other functions as appropriate), and then to call main() to do the
work.
Is that standard best practice?
Thanks
Congratulations on becoming a Pythonist!
Like Shambhu said, it doesn't matter where do you put the code, but is
interesting to have a main() function when you have a program, and you
want to differentiate if it is running directly (i.e. python program.py)
or if it is running as a module, imported by other program (i.e. import
program).
To do so, you do this:
main():
# blablabla
if __name__ == '__main__':
main()
If the program is running directly, the variable __name__ will be
'__main__', if not, __name__ will be the name of the module ('program',
in this case).
Att;
Pedro
