A comprehensive Python code analysis web application built with Flask. This app allows users to input Python code and receive detailed feedback from multiple analysis tools.

Features

• Syntax Checking: Validates Python syntax using AST
• Code Quality Analysis: Pylint for comprehensive code quality assessment
• Style Enforcement: Flake8 for PEP 8 compliance
• Type Checking: MyPy for static type analysis
• Security Scanning: Bandit for security vulnerability detection
• Modern UI: Apple-inspired design with smooth animations
