How to run turtle scripts within Spyder

Option 1

Call turtle.done() with turtle.bye() and use the Inline or Automatic backend for the IPython Console (Preferences > IPython Console > Graphics > Graphics Backend). As an example:

import turtle

wn=turtle.Screen()
wn.bgcolor("lightgreen")
tess = turtle.Turtle() # Create tess and set some attributes
tess.color("hotpink")
tess.pensize(5)
alex = turtle.Turtle() # Create alex

tess.forward(80) # Make tess draw equilateral triangle
tess.left(120)
tess.forward(80)
tess.left(120)
tess.forward(80)
tess.left(120) # Complete the triangle

alex = turtle.forward(100)

turtle.done()
turtle.bye()   

The call of turtle.bye() will raise a Terminator error but the IPython kernel will not die. To prevent the output of the exception you can use a try/except, like this:

...
turtle.done()
try:
    turtle.bye()   
except turtle.Terminator:
    pass

The reason for this is to clean some elements used by Turtle after running.

Important note: The try/except block is only needed if the Spyder version is less than 3.3.3.

Option 2

Instead of using the IPython Console you can use an external system terminal. Go to Run > Configuration per file... > Select Execute in an external system terminal over the Console section.
