Pyflakes
A simple program which checks Python source files for errors.
Pyflakes analyzes programs and detects various errors. It works by
parsing the source file, not importing it, so it is safe to use on
modules with side effects. It's also much faster.
It is available on PyPI <https://pypi.org/project/pyflakes/>_
and it supports all active versions of Python: 2.7 and 3.4 to 3.7.
Installation
It can be installed with::
$ pip install --upgrade pyflakes
Useful tips:
- Be sure to install it for a version of Python which is compatible
with your codebase: for Python 2,pip2 install pyflakesand for
Python3, pip3 install pyflakes.
- You can also invoke Pyflakes with
python3 -m pyflakes .orpython2 -m pyflakes .if you have it installed for both versions. - If you require more options and more flexibility, you could give a
look to Flake8_ too.
Design Principles
Pyflakes makes a simple promise: it will never complain about style,
and it will try very, very hard to never emit false positives.
Pyflakes is also faster than Pylint_
or Pychecker_. This is
largely because Pyflakes only examines the syntax tree of each file
- As a consequence, Pyflakes is more limited in the
- of things it can check.
If you like Pyflakes but also want stylistic checks, you want
flake8_, which combines
Pyflakes with style checks againstPEP 8_ and adds
per-project configuration ability.

Contributing
Issues are tracked on GitHub <https://github.com/PyCQA/pyflakes/issues>_.
Patches may be submitted via a GitHub pull request_ or via the mailing list
if you prefer. If you are comfortable doing so, please rebase your changes_
so they may be applied to master with a fast-forward merge, and each commit is
a coherent unit of work with a well-written log message. If you are not
comfortable with this rebase workflow, the project maintainers will be happy to
rebase your commits for you.
All changes should include tests and pass flake8_.
