It would appear that you are calling this function and rescanning scanning 
file for each number.  It would be more efficient to scan the file once, 
for each line parsing out the number and minutes and incrementing the 
minutes for that number.

Also, if you had printed repr(li[5]) and len(li[5]) instead of or in 
addition to just li[5] (which prints str(li[5]),
"2" '"2"' 3

you might have seen for yourself the problem that the string contains quote 
marks and not just digits.  Repr and len are useful debugging aids.
