COMPUTER SOFTWARE APPLICATION - CITS

This Python-style pseudocode describes the main components of Python’s architecture:

• Interpreter: Responsible for executing Python code by coordinating different components like parsing,
compiling, and executing.
• Standard Library: Contains built-in modules and functions that provide a wide range of functionalities.
• Bytecode Compiler: Translates parsed Python code into bytecode, which is then executed by the virtual
machine.
• Parser: Converts source code into an abstract syntax tree (AST) for further processing.
• Execution Engine: Executes bytecode within a virtual machine environment.

• Memory Manager: Allocates and manages memory for Python objects.
• Object Model: Defines the structure and behavior of Python objects.
• Garbage Collector: Identifies and frees memory occupied by unused objects to prevent memory leaks.
This architecture demonstrates how Python processes code from source to execution, handling memory
management and providing a rich set of functionalities through its standard library and object model.
