## Introduction

Write a Python function that prints out the first n rows of Pascal’s triangle. I have used python 3.7 compiler for debugging purpose.

def pascal_triangle(num): trow = [1] y = [0] for x in range(max(num,0)): print(trow) trow=[l+r for l,r in zip(trow+y, y+trow)] return num>=1 pascal_triangle(5)
