As I expected, a dictionary lookup is a _little bit_ slower (3%) between Python 3.5 and Python 3.6:
$ ./python -m perf timeit -s 'd={str(i):i for i in range(100)}' 'd["10"]; d["20"]; d["30"]; d["40"]; d["50"]; d["10"]; d["20"]; d["30"]; d["40"]; d["50"]' --rigorous
Median +- std dev: [lookup35] 309 ns +- 10 ns -> [lookup36] 320 ns +- 8 ns: 1.03x slower |
