Answer 2

Answer :

Here's a Python program to print the square of all even numbers from 1 to 20:

for i in range(2, 21, 2):

   print(i**2)

Explanation:

This program uses a for loop to iterate over the range of numbers from 2 to 20 with a step size of 2. This ensures that only even numbers are considered. The ** operator is used to calculate the square of each even number, which is then printed to the console.

Alternatively, we can use a list comprehension as follows:

squares = [i**2 for i in range(2, 21, 2)]

print(squares)

This program creates a list of squares of all even numbers from 1 to 20 using list comprehension and then prints it.

Both programs produce the same output:

4

16

36

64

100

144

196

256

324

400

Note that we start the range from 2 instead of 1 because we want only even numbers.
