Hello everyone!
I have 2 text files with some number ranges, e.g.: 
100000313-100001222

[download]
in one file and 100000391-100000947 in the other.
My goal is to take each line from each file and see if it is somehow "contained" in the other. As you can see from the example, the range 100000391-100000947 is within the range 100000313-100001222.
Can you provide me with some help as to how I can deal with such a problem?
Is there some module or something?
Thank you very much for your time!
