Sounds wise?
Its an acceptab;e approach bwhen you are doing exactly
the same thing, but its not a very flexible approach and
leaves you very vulnerable if you get a change that only
applies to one of your solutions.
I thought if I converted it to a function or a class would make
it more flexible,
A set of functions is probably sufficient from the sounds
of things. That way you can mix n match the functions,
pass in different arguments etc to get the same
functionality but with more control.
functions out of everything. I'm still too much attached to
procedural, not functional programming, if I understand the terms
correctly.
procedural programming is where you use procedures
or functions to accomplish the task. You link those functions
together, either in a top level function or in global level cotrol
script. This is also (more correctly) known as imperative style
programming.
functional programming is quite different and comprises
a set of rules about how the code should be structured.
In functional programming the whole program is a function
that returns a value. Every function should return a value and
functions should not alter any global data. Every function
should ideally be an expression. No stateful constructs
such as loops or assignment statements should be used
(repetition is done via recursion). In practice most folks
relax the rules a little and allow simple loops (ie using
a counter as in
for n in range(n))
and some assignments. But the ideal is to build a program with
no state and everything done as an expression with nested sub
expressions. It is very closely aligned with formal methods in
Computer Science and formal languages such as Z or VDM
For most programmers functional programming is at least
as big a conceptual leap from procedural or imperative
programming as OOP.
I'll comment on the code separately.
