""" pyramid.py ===== A Pyramid of Numbers ----- Write a program that creates a pyramid of numbers with the left side of the pyramid counting down, and the right side of the pyramid counting up. Note the alignment of the numbers. Requirements ----- * Ask the user for a number * You can assume the input is a valid integer * However, if it's 0 or less, ask for the height again * Generate a pyramid made of numbers based on user input  * Mimic the pyramid in the example output below * Ensure that the spacing between each number is consistent * It may be useful to widen the output window (make it horizontal) * Hint: nested loops may be helpful * Hint: if you need it, there's a built in function to calculate absolute value: abs * abs(-5) # returns 5 * Hint: some of these string related operators and functions may be helpful: * repetition operator * format function * len function * str function Example 1: ----- Enter the height of your pyramid  >-2 Enter the height of your pyramid  >-5 Enter the height of your pyramid  >3 1 2 1 2 3 2 1 2 3 Example 2: ----- Enter the height of your pyramid  >12 1 2 1 2 3 2 1 2 3 4 3 2 1 2 3 4 5 4 3 2 1 2 3 4 5 6 5 4 3 2 1 2 3 4 5 6 7 6 5 4 3 2 1 2 3 4 5 6 7 8 7 6 5 4 3 2 1 2 3 4 5 6 7 8 9 8 7 6 5 4 3 2 1 2 3 4 5 6 7 8 9 10 9 8 7 6 5 4 3 2 1 2 3 4 5 6 7 8 9 10 11 10 9 8 7 6 5 4 3 2 1 2 3 4 5 6 7 8 9 10 11 12 11 10 9 8 7 6 5 4 3 2 1 2 3 4 5 6 7 8 9 10 11 12 """
