⏳ Timer for Python ⌛️

Lightweight Python package that makes it easy to measure how much time it takes to run Python programs and gauge performance of multiple, smaller bits of code.

Getting Started

Basics

Simply add the Timer to your imports, and then wrap the Timer function around your code to measure the performance of the executed block of code:

from timer import Timer

timer = Timer()
timer.start()

# Insert your code here

timer.stop() # Output example: 12.34 seconds

Context Manager

Alternatively, use the with statement. This will automatically start and stop the clock – and so no need to declare timer.start() and timer.stop(). Same result as before, but less code:

with Timer():
    # Insert your code here

    # Output example: 12.34 seconds

Decorator

Or use the function_timer as a function decorator:

from timer import function_timer

@function_timer()
def test_function():
    # Insert your code here

test_function()

# Output example: 12.34 seconds for thread TEST_FUNCTION

Core Features

Decimals

Instead of the default value of 2 for decimals``, you can set the output precision up to 9in thedecimals` parameter:

timer = Timer()
timer.start(decimals=5)

# Insert your code here

timer.stop() # Output example: 0.12345 seconds

Multiple Threads

Imagine that you want to troubleshoot which parts of your code are performing better or worse. Or do you want to split-test the performance of different methods? Timer for Python is a quick, easy way to get the job done.

To measure the performance of multiple blocks of code, use the thread parameter to name different threads:

timer = Timer()
timer.start(thread="A")

# Insert your code here

    timer.start(thread="B", decimals=5)

    # Insert more code here

    timer.stop(thread="B") # Output example: 0.12345 seconds for thread B

# Insert even more code here

timer.stop(thread="A") # Output example: 6.78 seconds for thread A

Or use the with statement to get the same result with less code:

with Timer(thread="A")
    # Insert your code here

    with Timer(thread="B", decimals=5):
        # Insert more code here

        # Output example: 0.12345 seconds for thread B

    # Insert even more code here

    # Output example: 6.78 seconds for thread A
