Code Explanation:

Function Definition

def print_even_numbers():

def is used to define the function.

print_even_numbers is the function name.

It does not take any parameters, since the range is fixed (1 to 20).

Docstring (Optional but Recommended)

"""This function prints all even numbers from 1 to 20."""

Describes what the function does.

Helps in documentation and debugging.

Using the range() Function

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

range(start, stop, step) generates a sequence of numbers:

2 → Start from 2 (first even number).

21 → Stop before 21 (last number is 20).

2 → Step by 2 (only even numbers).

The loop runs:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

Printing the Numbers

print(num, end=" ")

Prints each number on the same line with a space (end=" ").

Output:

2 4 6 8 10 12 14 16 18 20

Calling the Function

print_even_numbers()

Calls the function, and it prints:

2 4 6 8 10 12 14 16 18 20
