turtle.begin_fill()
turtle.color('red')
turtle.fillcolor('yellow')
turtle.circle(50,steps=6)
turtle.end_fill()
turtle.hideturtle()

import turtle

turtle.fillcolor('yellow')
turtle.circle(50,steps=6)
turtle.end_fill()
turtle.hideturtle()

import turtle
turtle.pensize(5)
turtle.fillcolor('red')
turtle.begin_fill()

turtle.circle(50,steps=6)
turtle.end_fill()
turtle.hideturtle()
