# Bad code

def func1(x1,x2):
    for i in range(d):
    return e
# Refactored and optimized code

def sum_and_multiply(x1, x2):
    # Rename variables to be more descriptive
    num1 = x1
    num2 = x2

    # Calculate the sum and multiply it by 10
    total_sum = num1 + num2
    multiplied_sum = total_sum * 10

    # Create an empty list to store the results
    result_list = []

    # Iterate through the range of the multiplied sum
    for i in range(multiplied_sum):
        # Append the double of each value to the list
        result_list.append(i * 2)

    return result_list
