In the previous unit, we explored inheritance. Now let's look at two more OOP concepts: encapsulation and polymorphism. Encapsulation controls access to an object's data. Polymorphism lets different classes share a common interface.

In the previous unit, we explored methods and the difference between class and instance variables. Now let's look at inheritance, which lets a class inherit attributes and methods from another class.

In the previous unit, we introduced classes and objects. Now let's dig deeper into methods, functions that live inside classes, and understand the difference between class variables and instance variables.

In the previous unit, we learned about file operations. Now let's explore Object-Oriented Programming (OOP), a way of organizing code around objects that represent real-world entities.

In the previous unit, we learned about dictionaries. Now let's explore file operations: how to read data from files and write data to files so your programs can persist information.

In the previous unit, we explored ranges, sets, and tuples. Now let's look at dictionaries, Python's way of storing data as key-value pairs.

In the previous unit, we learned about list comprehension. Now let's explore three more data structures: ranges, sets, and tuples. Each has different properties that make it useful in specific situations.

In the previous unit, we learned how to create and manipulate lists. Now let's look at list comprehension, a concise way to generate lists in a single line.

In the previous unit, we explored string operations. Now let's look at lists, Python's way of storing multiple values in a single variable.

In the previous unit, we explored Python's built-in functions. Now let's look at strings, one of the most common data types you'll work with.
