How do different programming languages handle configuration files?

Different programming languages have various methods for handling configuration files. For example, Python often uses JSON or YAML, while Java might use XML or properties files.

Can you give me an example of a YAML config file in Python?

Sure! Here's a simple example of a YAML config file in Python:

settings:
  debug: true
  database:
    host: localhost
    port: 5432

You can use the PyYAML library to read this file in your Python code.

What about configuration in Java? How does it differ?

In Java, configuration is often done using properties files or XML. A properties file might look like this:

# Database configuration
host=localhost
port=5432

Java's Properties class can easily load these files.

Are there any best practices for managing config files?

Yes, some best practices include keeping sensitive information out of version control, using environment variables for sensitive data, and organizing configurations by environment (development, testing, production).
