Question

6 essay 10 points how would you write a function that takes a list of numbers and returns a new list containing only the even numbers?

Explanation:

Step1: Define the function

Define a function, say get_even, that takes a list nums as a parameter.

def get_even(nums):

Step2: Initialize an empty list

Create an empty list to store the even numbers.

    result = []

Step3: Iterate through the input list

Loop through each number in the input list nums.

    for num in nums:

Step4: Check for even numbers

Use the modulus operator % to check if a number is divisible by 2 (i.e., even). If num % 2 == 0, append it to the result list.

        if num % 2 == 0:
            result.append(num)

Step5: Return the result

After processing all numbers in the input list, return the result list containing only the even numbers.

    return result

Answer:

def get_even(nums):
    result = []
    for num in nums:
        if num % 2 == 0:
            result.append(num)
    return result

(You can also use a list comprehension: def get_even(nums): return [num for num in nums if num % 2 == 0])
