Answer to Question #298633 in Python for leigh

Question

Write a program that draws the three shapes as illustrated in figure 4.2. Think about the concept of composition discussed in chapter 3. Create several smaller functions to perform the basic tasks. Use those functions to build more complicated functions until you have achieved the stated goal.

Answer 1

def drawTriangle(n):
    triangle = []
    if n % 2 == 1:
        for i in range(n):
            triangle.append(' ' * i + '*' * (n - i * 2) + ' ' * i)
        triangle.reverse()
        for i in triangle:
            print(i)
        print('\n')
    else:
        print('N must be odd to draw a triangle')

def drawRectangle(a, h):
    for i in range(h):
        print('*' * a)
    print('\n')

def drawRhombus(n):
    if n % 2 == 1:
        for i in range(1,n,2):
            str = ' ' * ((n-i)//2)  + '*' *i + ' ' * (n-i)
            print (str)
        for i in range(n,0,-2):
            str = ' ' * ((n-i)//2)  + '*' *i + ' ' * (n-i)
            print (str)
        print('\n')
    else:
        print('N must be odd to draw a rhombus')

drawTriangle(11)
drawRectangle(10, 5)
drawRhombus(11)
