10. Print Even Numbers from a Given List

Write a Python program to print the even numbers from a given list.

Sample Solution:

Python Code:

# Define a function named 'is_even_num' that takes a list 'l' as input and returns a list of even numbers
def is_even_num(l):
    # Create an empty list 'enum' to store even numbers
    enum = []
    
    # Iterate through each number 'n' in the input list 'l'
    for n in l:
        # Check if the number 'n' is even (divisible by 2 without a remainder)
        if n % 2 == 0:
            # If 'n' is even, append it to the 'enum' list
            enum.append(n)
    
    # Return the list 'enum' containing even numbers
    return enum

# Print the result of calling the 'is_even_num' function with a list of numbers
print(is_even_num([1, 2, 3, 4, 5, 6, 7, 8, 9])) 
 

Sample Output:

[2, 4, 6, 8] 

Explanation:

In the exercise above the code defines a function named "is_even_num()" that takes a list of numbers as input and returns a new list containing only the even numbers from the input list. It iterates through the input list and checks whether each number is even. If a number is even, it adds it to a new list called 'enum'. Finally, it tests the function by calling it with a list [1, 2, 3, 4, 5, 6, 7, 8, 9] and prints the resulting list of even numbers.

• Write a Python function that iterates over a list and prints elements that are even, using the modulo operator.
• Write a Python function that uses list comprehension to create and return a new list containing only the even numbers.
• Write a Python function that filters a list using the filter() function with a lambda to keep even numbers.
• Write a Python function that sorts a list and then extracts and prints the even numbers using slicing with a step.
