Time a block of code
Time a block of code.
Use as the context expression of a
>>> from harrison import Timer >>> with Timer() as t: >>> ... >>> print(t.elapsed_time_ms) 12345
When a description string is passed on initialization, the elapsed time will be printed on completion, keyed by this description.
>>> with Timer('My expensive block of code'): >>> ... My expensive block of code: 12345 ms
You can also start and stop a Timer explicitly:
timer = Timer() timer.start() some_expensive_function(...) print(timer.elapsed_time_s) another_expensive_function(...) timer.stop() print(timer.elapsed_time_s)
You can also time each execution of a function using a decorator:
from harrison import profile @profile('Describes the function') def some_function(): pass # Without args, the function name (e.g. 'some_function') will be used # as the description. @profile() def another_function(): pass
You can also use
RegisteredTimer, which groups together a bunch of named
timers, provides utilities for serializing their times, and an optional global
Named after John Harrison, the English carpenter and clockmaker who invented the marine chronometer.
This is similar to the library contexttimer, but that library is licensed under the GPLv3 which is more restrictive than two-clause BSD license used here.
