90 Python Static Analysis Tools
What is Python?
Python is an interpreted, high-level and general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Python is dynamically typed and garbage-collected. It supports multiple programming paradigms, including structured…

SonarQube
SonarQube is an open platform to manage code quality.
pylint
Looks for programming errors, helps enforcing a coding standard and sniffs for some code smells. It additionally includes `pyreverse` (an UML diagram generator) and `symilar` (a similarities checker).
ShiftLeft
Identify vulnerabilities that are unique to your code base before they reach production. Leverages the Code Property Graph (CPG) to run its analyses concurrently in a single graph of graphs. Automatically finds business logic flaws in dev like hardcoded secrets and logic bombs
DeepSource
In-depth static analysis to find issues in verticals of bug risks, security, anti-patterns, performance, documentation and style. Native integrations with GitHub, GitLab and Bitbucket. Less than 5% false positives.
Better Code Hub

lizard
Lizard is an extensible Cyclomatic Complexity Analyzer for many programming languages including C/C++ (doesn't require all the header files or Java imports). It also does copy-paste detection (code clone detection/code duplicate detection) and many other forms of static code analysis. Counts lines of code without comments, CCN (cyclomatic complexity number), token count of functions, parameter count of functions.
