Let's dive into Python Dictionaries for beginners: What are Python Dictionaries? Imagine a regular dictionary where you look up words and their definitions. Python dictionaries work similarly, but they store information in key-value pairs. Keys: Think of these as unique labels or identifiers for your information. Keys must be immutable (unchangeable) data types like strings, numbers, or tuples. Values: This is the actual data you want to store. Values can be any data type, including strings, numbers, lists, or even other dictionaries (we'll get to that later). Creating Dictionaries: There are two main ways to create dictionaries in Python: Curly braces: This is the most common way. You place your key-value pairs enclosed in curly braces {}, separated by commas. Here's an example: Python person = {"name": "Alice", "age": 30, "city": "New York"} Use code with caution. content_copy In this example, "name", "age", and "city" are the keys, and "Alice", 30, and "New York" are the corresponding values. dict() function: This is a built-in function that allows you to create dictionaries explicitly. You can pass key-value pairs as arguments or use keyword arguments. Here's an example:
