16. Create and Print a List of Squares for Numbers 1 to 30

Write a Python function to create and print a list where the values are the squares of numbers between 1 and 30 (both included).

Sample Solution:

Python Code:

# Define a function named 'printValues' that generates a list of squares of numbers from 1 to 20
def printValues():
    # Create an empty list 'l'
    l = list()
    
    # Iterate through numbers from 1 to 20 (inclusive)
    for i in range(1, 21):
        # Calculate the square of 'i' and append it to the list 'l'
        l.append(i**2)
    
    # Print the list containing squares of numbers from 1 to 20
    print(l)

# Call the 'printValues' function to generate and print the list of squares
printValues() 

Sample Output:

[1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400]

Explanation:

In the exercise above the code defines a function named "printValues()" that generates a list of squares of numbers from 1 to 20. It iterates through a range of numbers from 1 to 20, calculates the square of each number, and appends it to an initially empty list l. Finally, it prints the list containing squares of numbers from 1 to 20 by calling the "printValues()" function.
