turtle.bye(), aka turtle.Screen().bye(), closes a turtle graphics window. Usually, a lack of turtle.mainloop(), or one of its variants, will cause the window to close because the program will exit, closing everything. turtle.mainloop() should be the last statement executed in a turtle graphics program unless the script is run from within Python IDLE -n which disables … Read more
Your turtle program is structured incorrectly. You needn’t do: tw = t.Screen() … tw.exitonclick() in every function. Screen() only needs to be called once; exitonclick() should only ever be called once. Try this restructuring: import turtle as t def square(): for i in range(4): t.forward(100) t.right(90) def triangle(): for i in range(3): t.forward(100) t.right(120) def … Read more
Rounding up Ignacio’s answer and orokusaki’s comment you probably should write something like import turtle class TurtleGTX(turtle.Turtle): “””My own version of turtle””” def __init__(self,*args,**kwargs): super(TurtleGTX,self).__init__(*args,**kwargs) print(“Time for my GTX turtle!”) my_turtle = TurtleGTX() my_turtle.forward(100)
You’ve made a common error that I happended to also make when I was investigating your question. I assume you have your code written in a file called ‘turtle.py‘? When you import turtle, it imports your file, not the turtle library. Rename your file to something other than turtle.py, and your code should run fine. … Read more
from tkinter import * # Python 3 #from Tkinter import * # Python 2 import turtle turtle.forward(100) ts = turtle.getscreen() ts.getcanvas().postscript(file=”duck.eps”) This will help you; I had the same problem, I Googled it, but solved it by reading the source of the turtle module. The canvas (tkinter) object has the postscript function; you can use … Read more
I’m skeptical that you can cleanly solve this coordinating variables between onkeypress() and onkeyrelease() events. (Though I’d be pleased to be shown otherwise.) I offer an alternate approach where key presses simply post move requests and a timer applies those requests, whether individual or doubled up: from turtle import Turtle, Screen win = Screen() flynn … Read more
This code seems to be more wishful thinking than actual programming: def is_collided_with(self, run): return self.rect.colliderect(run.rect) runner = run(10, 10, ‘my_run’) follower = follow(20, 10) if follow.is_collided_with(run): print ‘collision!’ Turtles don’t have a .rect() method. You can’t simply add a is_collided_with() method to an existing class with this def statement. There are no run() and … Read more
I think you’ve actually got a wider confusion here. The initial error is that you’re trying to call split on the whole list of lines, and you can’t split a list of strings, only a string. So, you need to split each line, not the whole thing. And then you’re doing for points in Type, … Read more

You may be able to build and compile some application to run on the client machine, but modern web browsers do not have the ability to run python files. As mentioned in the comments, you’d have to get user input and then process it server side.
