Assignment $3$A: Pattern Generator

Write a Python program that prompts the user for a positive integer and prints a pyramid pattern

with numbers.

Instructions:

$1.$ Prompt the user for a positive number

$2.$ Print out as many rows as that positive number indicates. For example, if the user enters

$4,$ you'll print out $4$ rows of numbers. If the user enters $15,$ you'll print out $15$ rows of

numbers.

$3.$ Each row should be made up of numbers counting from $1$ left to right. Each row should

have exactly as many numbers on it as the row number. For example, row $1$ will have $1$

number, row $4$ will have $4$ numbers.
