Practical Python: Learn Python Basics Step by Step- Python 3 - Python Level 2: Exercises – Solution

This video tutorial covers four exercises in a Level 2 course. The first exercise involves asking for a user's name and age and printing the information. The second exercise focuses on adding two integers and printing the result. The third exercise involves creating a list of numbers, computing their average, and printing it. The final exercise demonstrates converting Celsius to Fahrenheit using a function. Each exercise is explained with code examples and tips for writing clean, readable code.

What is the primary task in the first exercise of Level 2?

• To convert Celsius to Fahrenheit

• To ask for the user's name and age and print the information

• To compute the average of a list

• To calculate the sum of two numbers

Which of the following is a correct way to define a function that adds two numbers?

• def add_numbers(a, b): return a + b

• def add_numbers(a, b): return a - b

• def add_numbers(a, b): return a * b

• def add_numbers(a, b): return a / b

Why is it necessary to cast user input to an integer when adding two numbers?

• Because input is always a float

• Because input is always a string

• Because input is always a boolean

• Because input is always an integer

What is the purpose of the 'compute_list_average' function?

• To sort a list of numbers

• To compute the average of a list of numbers

• To find the maximum number in a list

• To find the minimum number in a list

In the context of the 'compute_list_average' function, what is the significance of variable scope?

• It changes the value of the variable

• It defines where a variable can be accessed within the code

• It affects the performance of the function

• It determines the data type of the variable

What is the correct formula to convert Celsius to Fahrenheit?

• Celsius + 32

• Celsius / 1.8 + 32

• Celsius * 1.8 + 32

• Celsius * 1.8

Why is it important to ensure parentheses are correctly placed in the Celsius to Fahrenheit conversion function?

• To increase the accuracy of the conversion

• To make the code look cleaner

• To avoid syntax errors and ensure correct calculation

• To ensure the function runs faster
