What is PyYAML? A Python YAML Parser & Emitter..

PyYAML is a Python library used for working with YAML (YAML Ain’t Markup Language), a human-readable format commonly used for configuration files and data exchange.

As a parser, PyYAML can read YAML documents and convert them into Python data types like dictionaries, lists, strings, and numbers. As an emitter, it can take Python objects and write them out as properly formatted YAML text.

🔑 Key Points:
Parser: Converts YAML into native Python objects.

Emitter: Converts Python objects into YAML format.

Use Cases: Configuration files, data serialization, APIs, and application settings.

Human-Readable: YAML is more readable than JSON or XML, making it popular for configs.

Safe Loading: PyYAML provides secure methods to prevent code execution when reading untrusted YAML files.

In essence, PyYAML acts as a bridge between YAML files and Python applications, enabling easy reading, manipulation, and writing of structured data in a clean and efficient way.
