You'd find it a lot easier to get responses if you'd say in what way the 
code is wrong.  If you get an exception, show the full traceback.  If 
you get printed results, show what you expected, and what you got 
instead.  If it hung, or crashed the OS, or ran out of memory, say so.

What did you expect this to do?  What is bigList[2] ?  What is 
bigList[int(sqrt(num)) + 1] ?  Are these reasonable values to put into a 
range() function?
