This package provides machine-readable type hints (stubs) for the popular `tqdm` progress bar library. It enables static type checkers like MyPy, Pyright, or Pylance to validate `tqdm` usage in Python code, catching potential type errors before runtime. As part of the `typeshed` project, `types-tqdm` versions are frequently released, often daily, to track changes and updates in the upstream `tqdm` library.

This quickstart demonstrates basic `tqdm` usage. Installing `types-tqdm` allows static type checkers (like MyPy, Pyright, or Pylance) to validate the type correctness of your interactions with `tqdm`'s functions and methods, for example, ensuring you pass an iterable to `tqdm` or correctly use its return values. The stubs themselves have no runtime effect; they are purely for static analysis.
Ensure both `tqdm` and `types-tqdm` are installed in your development environment (`pip install tqdm types-tqdm`).
Keep your `tqdm` and `types-tqdm` packages reasonably up-to-date. If you encounter unexpected type errors, try upgrading both packages to their latest versions, or pin `tqdm` to a version compatible with the `types-tqdm` stubs.
Add `pip install types-tqdm` to your CI/CD setup script before running the type checking command. Consider adding it to a `requirements-dev.txt` or similar file.
Use type checker directives (e.g., `# type: ignore` for MyPy) to suppress specific false-positive errors, but do so judiciously and with comments explaining why.
