Funtional Programming

Procedural Programming
num = 1
def procedure_to_add_one():
global num
num += 1
return num
procedure_to_add_one()
procedure_to_add_one()
procedure_to_add_one()
procedure_to_add_one()
procedure_to_add_one()
#Final Output: 6
function_to_add_one is a function
procedure_to_add_one is a procedure
Even if you run the function five times, every time it will return 2
If you run the procedure five times, at the end of fifth run it will give you 6.
DISCLAIMER: Obviously this is a hyper-simplified view of reality. This answer just gives a taste of "functions" as opposed to "procedures". Nothing more. Once you have tasted this superficial yet deeply penetrative intuition, start exploring the two paradigms, and you will start to see the difference quite clearly.
Helps my students, hope it helps you too.
