artimers

A utility package for timing and managing timers by Alexander Rießbeck

The goal of this package is it to provide easy to use timers that can collect timing data across your project and make the collected times accessible.

$ python -m pip install artimers

Usage

from artimers import Timer

Basics

Timer can be used in multiple ways

Class

Timer can be used as a class

timer = Timer()
timer.start()
...
final_time = timer.stop()

Decorator

Timer can be used as a decorator

@(timer:=Timer())
def foo():
    ...

print(timer)

Context Manager

Timer can be used as a context manager

with Timer() as timer:
    ...
    x = timer.time

Pretty print

Timer also has a custom __str__ method

timer = Timer()
timer.start()
sleep(0.2)
print(timer)
sleep(0.2)
timer.stop()
print(timer)

Timer (Running): 0.2004s
Timer (Stopped): 0.4007s

If the timer is named (Timer('Stopwatch 1')) the name will be used instead of Timer.

Printed decimals

The deciaml point used in the __str__ function can also be set (default is 4 and timing seems to be accurate up to 2)

timer = Timer(decimal=5)
print(timer)

Naming

Timer can be named and easily accessed later by using the same name again

Timer('Stopwatch 1')

Timer(name='Stopwatch 2')

Named timers always return the same instance and therefore keep their time and status (Running/Stopped).

Get timers

Timer can return a dict of all named timers

named_timers = Timer.get_timers()

Print results

The final time can be printed when exiting a decorator or context manager

@(Timer(print_result=True))
def foo():
    ...

with Timer(print_result=True):
    ...

Return results

The final time can also be return from a decorated function

@(Timer(return_result=True))
def foo():
    ...

time, _ = foo()
