Python is an interpreted, high-level programming language that follows a multi-paradigm approach. It supports procedural, object-oriented, and functional programming styles. The architecture of Python can be understood in several components:
Source Code:
Python source code is written in plain text files with a .py extension. These files contain the instructions and logic that define the program's behavior.
Interpreter:
The Python compiler is responsible for executing Python code. It reads the source code, parses it, and executes the instructions line by line. The interpreter is available as a standalone executable or as part of an integrated development environment (IDE).
Python Standard Library:
Python provides a comprehensive standard library that contains a wide range of modules and packages. These modules cover areas such as file I/O, networking, mathematics, data structures, regular expressions, and more. The standard library simplifies development by offering pre-built functionality that developers can leverage in their programs.

Python Virtual Machine (PVM):
The Python Virtual Machine, also known as the Python runtime environment, executes Python bytecode generated by the interpreter. It abstracts the underlying hardware and operating system, providing a platform-independent execution environment for Python programs.
Compiler:
The Python compiler is responsible for converting the human-readable source code into bytecode. It performs lexical analysis, syntax analysis, and generates an intermediate representation known as Abstract Syntax Tree (AST). The compiler optimizes the bytecode generation process by performing various transformations and optimizations.
Memory Manager:
Python employs automatic memory management through a garbage collector. The memory manager handles memory allocation and deallocation, allowing developers to focus on writing code without worrying about manual memory management.
Libraries and Packages:
Python has a vast ecosystem of third-party libraries and packages created by the community. These libraries extend the capabilities of Python by providing additional functionality for specific domains, such as scientific computing (NumPy, SciPy), web development (Django, Flask), data analysis (pandas), machine learning (scikit-learn, TensorFlow), and more.

Development Tools:
Python offers a variety of development tools, including Integrated Development Environments (IDEs) such as PyCharm, Visual Studio Code, and IDLE. These tools provide features like code editing, debugging, code completion, and project management to enhance the development workflow.
Overall, the architecture of Python revolves around the interaction between the source code, interpreter, virtual machine, standard library, and various supporting tools and libraries. Understanding this architecture helps developers write efficient and effective Python code while leveraging the language's rich ecosystem.
