Answer is 8 64

👉The code defines a Square class with a method getArea that calculates the area of a square using the side attribute.

👉An instance of the Square class is created which is obj, It has side = 8,

👉its area is calculated by calling getarea.

What will be the output of the following code:


my_list = [1, 2, 3, 4, 5]
print(my_list[1:4])

a) [1, 2, 3]
b) [2, 3, 4]
c) [2, 3]
d) [1, 3, 4]

P.S: Practice while learning
➤ Prerequisite: Know the History

Before start learning a language, read about its history.

❯ Why and how did it come into existence?
❯ How does it evolve over time?
❯ What are its alternatives?
❯ Where is it going to be a show-stopper?


➤ Prerequisite: Know the Ecosystem

❯ Which version you should be using?
❯ How to update to newer versions?
❯ Where would you write a program?
❯ How would you run a program?
❯ What additional software do you need?
❯ How would you include third-party libraries?


➤ Prerequisite: OS Challenge

Although the majority of languages strive to be similar across all operating systems, some dependencies may exist.

❯ Which installation package to download?
❯ How to install it?
❯ What are the different commands available?


🏁 Final Words

⬘ Though I have time bound it, you should try to cover everything based on your suitability.

⬗ Spend at least two hours per day learning and practicing.

⬙ With a proper structure and goal, it's never hard to learn Python.
