A custom timer utility for Python

Todd's Timer

A versatile and easy-to-use Python timer utility for measuring code execution time and analyzing performance.

Features

• Use as a decorator or context manager
• Nested timing support with proper indentation
• Detailed logging of start and end times
• Statistical analysis of execution times across multiple runs
• Customizable task names with support for dynamic formatting
• Lightweight and easy to integrate into existing projects

Installation

Install Todd's Timer using pip:

pip install todds_timer

Usage

At the top of your python file, import the Timer class and configure logging. Standard timing messages are logged at the DEBUG level, however the summary table produced by print_average_times() is at the INFO level.

from todds_timer import Timer
import logging

logging.basicConfig(level=logging.DEBUG, format="%(levelname)s %(message)s")

As a Context Manager

with Timer("Calculating sum"):
    result = sum([1,2,3,4])

Output:

DEBUG ----STARTED Calculating sum
DEBUG ----COMPLETED (in 0.000 seconds) Calculating sum

As a Decorator

@Timer("Calculate sum of {0} and {1}")
def add_numbers(a, b):
    return a + b

result = add_numbers(5, 7)

Output:

DEBUG ----STARTED Calculate sum of 5 and 7
DEBUG ----COMPLETED (in 0.000 seconds) Calculate sum of 5 and 7

Nested Timers

with Timer("Outer operation"):
    # Some code here
    with Timer("Inner operation"):
        # More code here
        pass

Output:

DEBUG ----STARTED Outer operation
DEBUG --------STARTED Inner operation
DEBUG --------COMPLETED (in 0.000 seconds) Inner operation
DEBUG ----COMPLETED (in 0.000 seconds) Outer operation

Analyzing Timing Results

# After running some timed operations
Timer.print_average_times(sort="name")

Output:

INFO Average | Minimum | Maximum | Count | Task name
INFO   0.000 |   0.000 |   0.000 |     1 | Calculate sum of 5 and 7
INFO   0.000 |   0.000 |   0.000 |     1 | Calculating sum
INFO   0.000 |   0.000 |   0.000 |     1 | Inner operation
INFO   0.000 |   0.000 |   0.000 |     1 | Outer operation

Configuration

Todd's Timer uses Python's built-in logging module. To see the timing output, ensure that your logging is configured to show DEBUG level messages:

import logging
logging.basicConfig(level=logging.DEBUG)
