verified Apr 11, 2026

Pyflakes is a fast, lightweight static analysis tool that meticulously checks Python code for common programming errors without executing it. It primarily identifies issues such as unused imports, undefined names, and redefined variables. Focusing solely on error detection, rather than code style, it aims for speed and minimizes false positives. Currently at version 3.4.0, Pyflakes supports Python 3.9 and newer, and is actively maintained by the PyCQA organization.
