I have to write a program which generates a pascal's triangle.
The user inputs the height of the triangle and it supposed to generate one.
This is what I have so far and I don't know how you would keep
adding rows after the second one. I'm so lost :(
numStr = raw_input("Please input the height of Pascal's Triangle: ") row = int(numStr) tri =  row1 =  row2 = [1, 1] tri.append(row1) tri.append(row2) while len(tri) < row: print tri break
