How does Python Work

Source Code: Python scripts are written using.py text files with Python-code in them.

Pylon interpreter: Software reads and executes Python programs by reading their source code files and translating into machine-readable instructions for execution.

Lexical Analysis: When running a Python application, tokenization lexical analysis occurs automatically. Keywords, identifiers, operators and literals from your source code are parsed out for further examination and parsed accordingly.

Parsing: Interpreters perform parsing after performing lexical analysis. An abstract syntax tree or parse tree is created based on token sequence data to ensure code conforms with Python syntax.

Compilation and Bytecode Generation: After creating the parse tree, the interpreter generates bytecode which will ultimately run-on Python Virtual Machine (PVM), with platform agnostic code stored as.pyc files for convenient execution.

Execution: Python Virtual Machine executes bytecode. PVM interprets and executes this bytecode while managing memory, variables, function calls, and any other runtime operations that might arise during execution.

Dynamic Typing: Python dynamically types variables at runtime using dynamic typing techniques. It automatically allocates and monitors variable types based on execution values for ease of use.

Standard Library and Modules: Python offers an expansive standard library, comprised of modules and packages tailored for many tasks ranging from file I/O and network connection management, mathematical computation, to file manipulation.

External Libraries and Packages: Python’s ecosystem of third-party modules and packages is vast, supporting data science, machine learning, web development, game design and much more. Installing or importing them into Python scripts using Pip is made effortless.

Output and Results: Python generates output based on code logic that displayed directly on a terminal, saved to files or presented otherwise.
