Procedural vs object-oriented approach in Python - Quick Revision & Key Differences

Recall & Review

beginner

What is the main idea behind the procedural programming approach?

Procedural programming organizes code as a sequence of instructions or steps, focusing on functions and procedures to perform tasks.

beginner

What does object-oriented programming (OOP) focus on?

OOP focuses on organizing code around objects that combine data and behavior, using concepts like classes, inheritance, and encapsulation.

How does procedural programming handle data and functions?

In procedural programming, data and functions are separate; functions operate on data passed to them as arguments.

intermediate

What is encapsulation in object-oriented programming?

Encapsulation means bundling data and methods that work on that data inside one unit (class), hiding internal details from outside code.

Give a simple example difference: How would you represent a 'Car' in procedural vs object-oriented style?

Procedural: Use separate functions like start_car(), stop_car() and variables for car data.<br>Object-oriented: Create a Car class with methods start() and stop() and attributes like color or speed.

Which programming approach groups data and functions together inside objects?

A Procedural programming

B Object-oriented programming

C Functional programming

D Declarative programming

Object-oriented programming groups data and functions inside objects called classes.

In procedural programming, how is the program mainly structured?

A As reactive components

B As objects with methods

C As a sequence of functions and procedures

D As database tables

Procedural programming structures code as a sequence of functions or procedures.

Which concept is NOT typically part of object-oriented programming?

A Recursion

B Encapsulation

C Inheritance

D Polymorphism

Recursion is a general programming technique, not specific to object-oriented programming.

What is a key benefit of using object-oriented programming?

A Better organization and reuse of code

B Easier to write short scripts

C Faster execution speed

D No need to write functions

OOP helps organize code better and promotes reuse through classes and inheritance.

In procedural programming, data is usually:

A Stored in classes

B Hidden inside objects

C Immutable

D Passed around to functions

Procedural programming passes data as arguments to functions.

Explain the main differences between procedural and object-oriented programming.

Think about how data and actions are organized in each approach.

Describe a simple example of how you would model a real-world object like a 'Car' in both procedural and object-oriented styles.

Imagine explaining to a friend how you would write code for a car using each style.
