About:
Vermin is a command-line tool that analyzes Python source code to concurrently detect the minimum required Python version. It identifies usage of language features and standard library modules to help developers ensure compatibility across different Python environments.

Key Features:

Concurrent processing for fast analysis
Detects Python 2.7 and 3.x version requirements
Identifies incompatible code patterns
Supports quiet and verbose output modes
Configurable via command-line flags

Use Cases:

Migrating legacy Python codebases to newer versions
Verifying compatibility before deploying applications
Auditing third-party libraries for version requirements
Enforcing minimum Python version standards in projects

Alternatives:

pyupgrade – pyupgrade automatically upgrades syntax, while Vermin detects version requirements without modifying code
caniusepython3 – caniusepython3 checks library dependencies, while Vermin analyzes language and stdlib feature usage
