Python: Generate and print a list of first and last 5 elements where the values are square of numbers between two numbers

Sample Solution:

Python Code:

# Define a function named printValues def printValues(): # Create an empty list 'l' l = list() # Loop 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 first 5 elements of the list 'l' print(l[:5]) # Print the last 5 elements of the list 'l' print(l[-5:]) # Call the printValues function to execute it printValues()

Sample Output:

[1, 4, 9, 16, 25] [256, 289, 324, 361, 400]

Explanation:

In the above example -

def printValues(): -> Defines a function named printValues.

l = list() -> Initializes an empty list named l.

for i in range(1,21): l.append(i**2)

Iterates through numbers 1 to 20 using a for loop and calculates their square, then appends the result to the l list.

print(l[:5]) -> Prints the first five elements of the l list using slice notation.

print(l[-5:]) -> Prints the last five elements of the l list using slice notation.

printValues() -> Finally calls the printValues() function. When executed, it will print the first five elements ([1, 4, 9, 16, 25]) and the last five elements ([256, 289, 324, 361, 400]) of the list of squares of numbers from 1 to 20.
