But when I run the onclick method, I get "TypeError: cannot unpack non-iterable NoneType object" before I even click anything. def on_click(x, y): t = turtle.Turtle() screen = turtle.Screen() t.penup() t.goto(x, y) #do stuff part 1 #do stuff part 2 return value1, value2 def main(): t = turtle.Turtle() screen = turtle.Screen()

问题 How would I undo something in the python turtle module? Here is my code: turtle.listen() turtle.onkey(undo, "ctrl + z") # You can't combine ctrl + z, so how do I do this? 回答1: turtle is built on top of tkinter and with the latter, a control-z can be specified with "<Control-KeyPress-z>". As stated by @martineau (+1) but with a minor correction of 'H' -> 'z'. You can't do it with the functions that turtle provides. Python turtle doesn't pass key press symbols directly onto tkinter, it appends

问题 Good afternoon, I am simulating a virus outbreak with the use of turtles.

问题 My text in my turtle module is not aligning properly, it is aligned up and to the left. I want it to align exactly where the turtle is. Can anyone help? I tried setting the xcor and ycor of the turtle up and to the left by 5 units and that did not work. Any help would be greatly appreciated. Code: import time from datetime import datetime,date import turtle t = turtle.Pen() while True: turtle.tracer(0, 0) hour_hand = float(datetime.today().hour) minute_hand = float(datetime.today().minute)

问题 I've been working with the turtle module and want to use it as a starting point to work on a simple image recognition program that could recognize numbers/letters. I need to be able to save the turtle as an image I could manipulate- recaling, rotating, etc. to try to regulate the images. I've been researching for hours and cannot seem to find anything that works. I have discovered how to save the Turtle output as a Tkinter canvas: import turtle t = turtle.Turtle() # Draw something canvas = t
