Write a Python program to find all index positions of the maximum and minimum values in a given list of numbers

def position_max_min(nums):
    max_val = max(nums)
    min_val = min(nums)
    max_result = [i for i, j in enumerate(nums) if j == max_val]
    min_result = [i for i, j in enumerate(nums) if j == min_val]
    return max_result,min_result

nums = [12,33,23,10,67,89,45,667,23,12,11,10,54]
print("Original list:")
print(nums)
result = position_max_min(nums)
print("\nIndex positions of the maximum value of the said list:")
print(result[0])
print("\nIndex positions of the minimum value of the said list:")
print(result[1])
