t.penup()

t.goto(x,y)

t.pendown()

def pen() :

pencolor = ['blue','black','red','yellow','green']

x = -450

y = 0

for i in range(5) :

if i == 3 :

x = -225

y = -150

if i < 3 :

go(x + i * 450,y)

t.pencolor(pencolor[i])

t.circle(200)

else :

go(x + ( i - 3 ) * 450, y)

t.pencolor(pencolor[i])

t.circle(200)

if __name__ == '__main__':
