Phone Book - Implementation

The code

Here's the solution:

phone_book = {}

phone_book["Alice"] = "555-1234"
phone_book["Bob"] = "555-5678"

print(phone_book["Alice"])  # 555-1234

Or build it in one line:

phone_book = {"Alice": "555-1234", "Bob": "555-5678"}

Adding entries is just assignment. The dictionary grows automatically.
