kids these days think data structures grow on trees

Args and kwargs are great features of Python.  There is a measurable (though highly variable) cost of them however:

>>> timeit.timeit(lambda: (lambda a, b: None)(1, b=2))
0.16460260000000204

>>> timeit.timeit(lambda: (lambda *a, **kw: None)(1, b=2))
0.21245309999999762


>>> timeit.timeit(lambda: (lambda *a, **kw: None)(1, b=2)) - timeit.timeit(lambda: (lambda a, b: None)(1, b=2))
0.14699769999992895


Constructing that dict and tuple doesn't happen for free:

>>> timeit.timeit(lambda: ((1,), {'b': 2})) - timeit.timeit(lambda: None)
0.16881599999999253


Specifically, it takes about 1/5,000,000th of a second.

  9. Going to graduate school was a positive decision for me. I enjoyed the coursework, the presentations, the fellow students, and the professors. And since my company reimbursed 100% of the tuition, the only cost that I had to pay on my own was for books and supplies. Otherwise, I received a free master’s degree. All that I had to invest was my time.
