What are some examples of using configuration files?

Can you give me some examples of how configuration files are used in software development?

Sure! Configuration files are used to set parameters and options for applications. For example, in a web application, a config file might specify database connection details.

What formats do these configuration files usually come in?

Common formats include JSON, YAML, and XML. Each has its own syntax and use cases depending on the application.

Can you show me a simple example of a JSON config file?

Absolutely! Here's a simple JSON config file:

{
  "database": {
    "host": "localhost",
    "port": 5432,
    "user": "admin",
    "password": "secret"
  }
}

How do I load this config file in a Python application?

You can use the json module in Python. Here's a quick example:

import json

with open('config.json') as config_file:
    config = json.load(config_file)
