Answer:
Here's a Python program that uses an initializer list to store the given set of numbers in a list named nums and then prints the first and last elements of the list:
Step-by-step explanation:
# Initialize a list named nums with the given set of numbers
nums = [56, 25, -28, -5, 11, -6]
# Print the first element of the list
print("First element:", nums[0])
# Print the last element of the list
print("Last element:", nums[-1])
The program outputs:
First element: 56
Last element: -6
