Stupid question, just need a quick and dirty fix

[Jordan Bayless]

I'm trying to modify some code to suit my purposes and I'm just trying to filter results as necessary. Basically, the code is returning one of a number from a subset of 150 numbers. I want to only do anything with it if the number is a 'good' one. I'm by no means a Python programmer (C# for me by trade) and I'm not looking for anything that will be distributed..I just want something that works.

Basically, here's what I'm trying to insert:

global blnDesiredInd

blnDesiredInd == False

if IDNum < 10:
    blnDesiredInd = True
if IDNum == 12:
    blnDesiredInd = True
if IDNum == 15:
    blnDesiredInd = True
if IDNum == 24:
    blnDesiredInd = True
if IDNum == 25:
    blnDesiredInd = True
if IDNum == 26:
    blnDesiredInd = True
if IDNum == 27:
    blnDesiredInd = True

    blnDesiredInd = True
if IDNum == 31:
    blnDesiredInd = True

    blnDesiredInd = True
if IDNum == 39:
    blnDesiredInd = True
if IDNum == 40:
    blnDesiredInd = True
if IDNum == 45:
    blnDesiredInd = True
if IDNum == 50:
    blnDesiredInd = True

    blnDesiredInd = True

    blnDesiredInd = True

    if blnDesiredInd == True:

I get various errors no matter what I do to this to try and make it work. Variable not defined. Referenced before assignment. etc etc. I'm lost. How do I make it work?
