  2. Challenge

    Write Two `for` Loops, with One Nested in the Other, to Draw a Pyramid

    length = 10
    astr = "*"
    for i in range(length):
        for j in range(length-i):
            print(" ", end='')
        astr += "**"

    length -= 1
    space = 1
    astrNum = ((length*2)-1)
    astr = "*" * astrNum
    for i in range(length):
        print(" " + space * " " + astr)
        astrNum -= 2
        astr = "*" * astrNum
        space += 1
