Python queries for CodeQL analysis

Explore the queries that CodeQL uses to analyze code written in Python when you select the default or the security-extended query suite.

Who can use this feature?

Code scanning is available for all public repositories on To use code scanning in a private repository owned by an organization, you must have a license for GitHub Advanced Security. For more information, see "About GitHub Advanced Security."

CodeQL includes many queries for analyzing Python code. All queries in the default query suite are run by default. If you choose to use the security-extended query suite, additional queries are run. For more information, see "CodeQL query suites."

Built-in queries for Python analysis

This table lists the queries available with the latest release of the CodeQL action and CodeQL CLI. For more information, see CodeQL change logs in the CodeQL documentation site.


GitHub autofix for code scanning is in beta. Functionality and documentation are subject to change. During this phase, the feature is restricted to alerts identified by CodeQL for private and internal repositories. If you have an enterprise account and use GitHub Advanced Security, your enterprise has access to the beta.
