How do I index dicts in Python for production systems?

In Python, indexing dictionaries is a fundamental operation that allows you to retrieve and manipulate data efficiently. This is especially useful in production systems where performance and data handling are critical. To access values in a dictionary, you typically use keys. Here's how you can do this effectively:

# Example of indexing a dictionary in Python data = { 'name': 'John Doe', 'age': 30, 'city': 'New York' } # Accessing values using keys name = data['name'] # Returns 'John Doe' age = data['age'] # Returns 30 city = data['city'] # Returns 'New York' # Handling missing keys with .get() method country = data.get('country', 'USA') # Returns 'USA' if 'country' key does not exist
