tqdm
Fast, Extensible Progress Meter
Decision gist · record as of 2026-08-14
Yes. tqdm is a mature, widely-adopted library with negligible install friction, no known vulnerabilities, active maintenance, and a single lightweight dependency. It solves a common problem—visualizing loop progress—with minimal code changes and near-zero performance cost. The dual MPL-2.0/MIT license is permissive for most use cases. Install it unless you have a specific reason to avoid copyleft licensing.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
tqdm is a lightweight progress-bar library that wraps any iterable and displays real-time feedback on iteration speed, completion percentage, and estimated time remaining. It works by inserting a single function call—tqdm(iterable)—between your loop and its data source, with negligible overhead (about 60ns per iteration). The library supports three main usage patterns: wrapping iterables directly, manual control via context managers or explicit update() calls, and command-line piping for monitoring shell commands and file operations.
The package is designed for universal compatibility: it runs on Linux, Windows, macOS, FreeBSD, NetBSD, and Solaris; works in plain terminals, IPython, and Jupyter notebooks; and requires only Python and basic terminal control characters (carriage return and line feed). It has one runtime dependency, colorama, which is needed on Windows for nested progress bars. The library is production-stable, actively maintained, and ranks in the top 100 PyPI packages by download volume.
Use it for
- Monitor long-running for-loops or list comprehensions to see iteration speed and remaining time without manual logging.
- Pipe tqdm between shell commands to display progress on file operations like tar, compression, or data processing pipelines.
- Track progress in Jupyter notebooks or IPython sessions with a visual bar that updates in-place without cluttering output.
- Manually control progress updates in tasks where iteration count is unknown upfront, using tqdm(total=N) and pbar.update().
- Nest multiple progress bars for hierarchical operations (e.g., outer loop over files, inner loop over records) with automatic line management.
