Why? If those micro benchmarks mattered in your domain, you wouldn't be using python.
To use a trivial example, using a set instead of a list to check membership is a very basic replacement, and can dramatically improve your running time in Python. Just because you use Python doesn't mean anything goes regarding performance.
The case is among the example numbers given in TFA:
"Dict lookup by key", "List membership check"
Does it have to spell out the difference is algorithmic in this case for the comparison to be useful?
Or, inversely, is the difference between e.g. memory and disk access times insignificant, because it's not algorithmic?
