How is it that you are opening the file, and iterating the contents?

What do you mean, "goes not responding"? What environment are you 
running in? Windows and IDLE?

Note that "not responding" isn't the same as crashing. If your program 
crashed, it would likely print on your terminal something like:

Traceback (most recent call last):
... lots of lines including useful information about the problem

or

Segmentation Fault

If it just goes "not responding" for a while in your tight loop, it 
could simply mean just that: your IDE or whatever is focusing so hard on 
running your program that there aren't any cycles to say "still here" to 
the OS, so the OS has no clue what's going on and says to the user "not 
responding".

Have you waited to see if it ever completes?
