stopwatch.py
A simple stopwatch for python
Decision gist · record as of 2026-08-14
Yes, if you need a minimal, dependency-free timer. The package is straightforward and well-suited for quick timing tasks. However, note that maintenance is dormant—no updates since 2022-09-04—so expect no bug fixes or Python version support beyond what is already declared. For production code or long-term projects, consider whether a more actively maintained alternative or Python's built-in timeit module better fits your needs.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.5 or later.
- Low install friction with no runtime dependencies.
- Dormant maintenance status since the latest release on 2022-09-04, though the repository remains active and unarchived.

What it is and what it does
Stopwatch.py wraps Python's time.perf_counter() in a simple object-oriented interface for measuring elapsed time. It provides a Stopwatch class that can be instantiated, started, stopped, reset, and queried for the elapsed duration in seconds or as a formatted string. The package has no external dependencies and runs entirely in-process—there is no background task or thread; timing is purely mathematical arithmetic on the counter values.
The package is designed for straightforward use cases where you need to measure how long a code block or operation takes. You can control decimal precision when converting to a string representation, and the stopwatch can be paused and resumed. It is lightweight enough for quick instrumentation but offers no advanced features like lap timing, multiple concurrent timers, or statistical aggregation.
Use it for
- Measure execution time of a function or code block during development or debugging.
- Track elapsed time in a game loop or animation to control frame timing.
- Benchmark performance of different algorithms or implementations.
- Monitor how long a background task or operation takes in a simple script.
