That may well be correct, at least in the case where the function passed to map is a builtin. 
Mapping a builtin to over a list is extremely fast. So write the code with a for loop so it is 
clear. When you identify a performance bottleneck you can try rewriting your loop using map or list 
comprehension, which is also fast. Until then it is premature optimization. For typical loops over a 
small number of items I can't imagine you would notice the difference.
