Turtle Graphics Help - Nate - Nov-14-2018
Hi, I'm trying to
fill each polygons with a different color and add side arrows to them, how would i do that?
thanks!
Here's an example of what i'm trying to accomplish
My current code: (Feel free to help me clean it up, any help will be appreciated <3)
import turtle
window = turtle.Screen()
window.bgcolor("white")
turtle = turtle.Turtle()
turtle.speed(300)
turtle.penup()
def drawingpoly() : #Polygon Drawings - 4 Angles
four = 4 # number of sides
five = 5 # number of sides
six = 6 # number of sides
seven = 7 # number of sides
eight = 8 # number of sides
x = -100 # x position
y = 200 # y position
turtle.goto(x, y) #move turtle to the coords above (x and y)
side_length = 150
angle = 360.0 / four #360 divided by sides
angle2 = 360.0 / five # 360 divided by sides
angle3 = 360.0 / six # 360 divided by sides
angle4 = 360.0 / seven # 360 divided by sides
angle5 = 360.0 / eight # 360 divided by sides
for i in range(four): #amount of repeats
turtle.pendown()
turtle.begin_fill()
turtle.forward(side_length)
turtle.right(angle)
turtle.end_fill()
for i in range(five): #amount of repeats
turtle.fillcolor('yellow')
turtle.begin_fill()
turtle.forward(side_length)
turtle.right(angle2)
turtle.end_fill()
for i in range(six): #amount of repeats
turtle.begin_fill()
turtle.forward(side_length)
turtle.right(angle3)
turtle.end_fill()
for i in range(seven): #amount of repeats
turtle.begin_fill()
turtle.forward(side_length)
turtle.right(angle4)
turtle.end_fill()
for i in range(eight): #amount of repeats
turtle.begin_fill()
turtle.forward(side_length)
turtle.right(angle5)
turtle.end_fill()
turtle.penup()
ans=True # Menu
loop=False #Loop option (true or false)
while ans:
print ("""
***************************
1. Draw polygons
2. Draw a flower
3. Exit
***************************
""")
ans=input ("Enter an option (1/2/3):")
if ans=="1":
print("Drawing polygons", drawingpoly())
elif ans=="2":
print("Drawing a flower")
elif ans=="3":
print("Exiting, see you again soon!")
exit()
window.exit()
elif ans !="":
print("Invalid Option. Try again")
window.exitonclick()
RE: Turtle Graphics Help - ichabod801 - Nov-14-2018
First of all, your figures aren't filling because you're starting and ending the fill every time you draw a side. That's because begin_fill and end_fill are inside your loops. You being the fill, draw a side, turn for the next side, then end the fill. And the penup being in the octogon loop is why it isn't getting drawn. Unindent that one level so the pen comes up after all of the sides are drawn, rather than coming up after the first (and every other) side is drawn.
Second, naming your turtle turtle blocks access to the turtle module. One line 1, the name turtle points to the turtle module. On line 4 you point it at an instance of the Turtle class. Now you have nothing pointing at the turtle module. It doesn't make a difference here, but it's bad programming style that could cause a problem in other programs you write. I would name your turtle instance something different and unique. Like george.
I would also just have one loop. Calculate the angle, and then loop through the number of sides. So it would look something like this:
angle = 360.0 / num_sides
george.pendown()
george.begin_fill()
for side in range(num_sides):
george.foward(side_length)
george.right(angle)
george.end_fill()
george.penup()Then you can either add a parameter named num_sides to the drawingpoly function, or you can put the above loop into another for loop that goes through 4 to eight sides.Note that to make the triangle shapes in the sample diagram, you would use george.stamp(). That would mean moving half of the length, stamping, and move the other half of the length.

That's what I was talking about in the sentence above your question.

No, seriously. Read the last line before your question.

Sorry, i'm extremely new to this. I really don't understand, is there a way you can assist me? I'm willing to pay per hour.

Hi, how can i fill each polygon with a different color? the current code i have only colors the drawings sides, but it doesn't fill the inside.
Thanks!

RE: Turtle Graphics Help - Filling each shape in - ichabod801 - Nov-26-2018
As I already said, and illustrated, you need to move the begin_fill and end_fill commands outside the loops. You are currently starting and ending the fill for each side. So each side is filled, but not the whole figure. You need to start the fill before you draw any sides (before the loop) and end the fill after you have drawn all of the side (after the loop).
