Dear tutors: this question is in continuation of my previous question about list manipulations where Kent and Bob helped me. Thanks to you both. My aim was to walk along coordinates of exon of a gene on a chromosome. In simple terms: Coordinates of a variable G1: a1 : 3-8 b2 : 10-25 c3 : 7-18

I would make list of all the numbers in the beginning and then just add numbers in a range to the list. It's much easier to test for something in a list than to compare each number with the previous one. Here is a example: import random def randnum():     c = []     l = len(c)        # Nu
