Practical Python: Learn Python Basics Step by Step- Python 3 - Lists

The video tutorial introduces the concept of lists in Python, highlighting their advantages over using multiple variables for storing related data. It demonstrates how to create a list, access and modify its elements, and append new items. The tutorial also emphasizes the importance of maintaining consistent data types within a list to avoid errors and maintain logical consistency.

Why is it impractical to use multiple variables for storing a large collection of data?

• It is easier to read.

• It uses less memory.

• It is faster to access data.

• It is more prone to errors and difficult to manage.

What is the correct way to create a list named 'temperatureList' with the values 12.3, 23.0, -12.8, and -5.9?

• temperatureList = [12.3, 23.0, -12.8, -5.9]

• temperatureList = {12.3, 23.0, -12.8, -5.9}

• temperatureList = (12.3, 23.0, -12.8, -5.9)

• temperatureList = '12.3, 23.0, -12.8, -5.9'

What will be the output of 'temperatureList[1]' if the list is [12.3, 23.0, -12.8, -5.9]?

• -12.8

• -5.9

• 23.0

• 12.3

What error occurs when you try to access an index that is not present in the list?

• Value Error

• Index Out of Range Error

• Type Error

• Syntax Error

How can you change the first element of a list named 'temperatureList' to 2.4?

• temperatureList[0] = 2.4

• temperatureList[1] = 2.4

• temperatureList.append(2.4)

• temperatureList.insert(0, 2.4)

Which function is used to add a new element to the end of a list?

• insert()

• add()

• append()

• extend()

Why is it recommended to use the same data type for all elements in a list?

• To make the list more readable.

• To save memory.

• To avoid errors and maintain logical consistency.

• To make the list faster.
