In Python GUI development, how do I handle configuration and secrets?

In Python GUI development, handling configuration and secrets is crucial for managing application settings and ensuring sensitive information is kept secure. One effective way to manage configurations is by using environment variables and configuration files. This approach separates sensitive data from your source code, reducing the risk of accidental exposure.

Example of Handling Configuration in Python

import os
import configparser

# Load configuration from a .ini file
config = configparser.ConfigParser()
config.read('config.ini')

# Accessing configuration values
database_user = config['database']['user']
database_password = os.environ.get('DB_PASSWORD', 'default_password')  # Get from environment variable

print(f'Connecting to database with user: {database_user}')
