Creating a Dictionary with Integer Keys and List Values

How can a dictionary be created with keys that are integers and values that are lists?

Which code segment creates a dictionary with keys that are integers and values that are lists?

Answer:

Code segment (B) correctly creates a dictionary with integer keys and list values. The syntax cards[1] = ["Ace", "Spades"] adds a key-value pair to the dictionary, where the key is an integer (1) and the value is a list ["Ace", "Spades"]. Similarly, cards[2] = ["Two", "Spades"] adds another key-value pair with an integer key (2) and a list value.

By utilizing the dictionary data structure, this code segment allows for efficient storage and retrieval of data with integer keys mapped to corresponding lists as values. It provides a convenient way to organize and access data based on integer keys, simplifying the process of working with key-value pairs within the dictionary.

Creating dictionaries with specific key-value pair configurations helps streamline data management tasks and enhances the overall efficiency of programming tasks that involve the storage and retrieval of structured information.

Understanding how to create dictionaries with desired key and value types is crucial for designing effective data structures in Python programming and optimizing the handling of information in various applications and scenarios.
