How Does Python Work?

Before learning hundreds of libraries, understand this simple architecture.

1. Your idea

"Create a 30-second video from these clips."

2. Python code

The instructions and decision-making logic

3. Libraries and tools

FFmpeg, video libraries, AI models, APIs

4. Output

A finished video file saved to disk

Python is the language you use to express the instructions. A library supplies reusable functionality, while an AI model supplies learned capabilities when needed. The computer executes the program and produces the result.

The official Python documentation explains the language, its built-in functionality, and its extensive ecosystem of third-party modules.
