Pylint
Pylint is a source code bug and quality checker for the Python programming language. It follows the style recommended by PEP 8, the Python style guide. It is similar to Pychecker but includes the following features:
- Checking the length of each line
- Checking if variable names are well-formed according to the project's coding standard
- Checking if declared interfaces are truly implemented
It is also equipped with the Pyreverse module that allows UML diagrams to be generated from Python code.
