Minitime

A tiny timing util that wraps around time.perf_counter_ns() under 40 LOC that can use to record functions and code snippet execution time.

Examples

To time a function:

from minitime import minitime

@minitime
def fib(n):
    if n <= 1:
        return n
    return fib(n - 1) + fib(n - 2)

fib(4)

output:
fib(1) took 1200ns
fib(0) took 1700ns
fib(2) took 129700ns
fib(1) took 3000ns
fib(3) took 237800ns
fib(1) took 2000ns
fib(0) took 3600ns
fib(2) took 184200ns
fib(4) took 570300ns

To time arbitrary code snippets:

from minitime import minitime_context

with minitime_context("code_1"):
    2 ** 1000000

output:
Code[code_1] took 3865300ns

You can even time the time function itself:

@minitime
@minitime
def f():
    pass
f()

Or

with minitime_context("1"):
    with minitime_context("2"):
        pass
