Python Mini-Compiler/Interpreter

A Python-based mini-compiler/interpreter with a Tkinter GUI that demonstrates various compiler phases including Lexical Analysis, Syntax & AST Analysis, Semantic Analysis, Intermediate Code Generation, Code Optimization, and Code Generation.

Features

• Interactive GUI with code editor and output display
• Support for Python-like syntax including:
  • Variables and assignments
  • Arithmetic operations
  • Control structures (if-else, while, for loops)
  • Function definitions and calls
  • Lists and string operations
  • Error handling (try-except)
  • Built-in functions (print, len, range)

Setup and Installation

1. Make sure you have Python 3.7+ installed
2. Install dependencies:

   pip install -r requirements.txt

3. Run the application:

   python script.py

Usage

1. Launch the application
2. Choose from the main options:
   • Learn Python
   • Test Your Skills
   • Optimize Code
   • Compiler Phases
3. Write your code in the editor
4. View the output and analysis in the respective panels

Compiler Phases

1. Lexical Analysis: Tokenizes input code
2. Syntax & AST Analysis: Builds Abstract Syntax Tree
3. Semantic Analysis: Type checking and validation
4. Intermediate Code Generation: Generates three-address code
5. Code Optimization: Performs optimizations like constant folding
6. Code Generation: Produces final output

Notes

• The interpreter supports a subset of Python features
• Error messages are displayed in the output panel
• The GUI provides real-time feedback for code analysis
