benchmarking parts of Pyhon

[Skaperen]

searching for benchmarking of Python i find tons of tutorials (he value of which i did not determine) and many tools to benchmark a function or application. what i want is benchmarks of discrete parts of Python, such as creating a tuple or creating a list (creating a tuple is somewhat faster than creating a list). next i want to test extracting from a tuple or list. i was looking to see if this kind of thing has already been done. i would think the developers might have done this but i could find nothing. do i need to develop something like this?
