So here is my problem, I have to make a picture for my CS class and it is really frustrating estimating in turtle. I planed to use .onclick() to show me to position. import turtle as t def getPos(x,y): print("(", x, "," ,y,")") return def main(): t.onclick(getPos) t.mainloop() main() The turtle documentation seems to say that the onclick will pass the coordinates in a function that takes in two variables. http://docs.python.org/3.1/library/turtle.html#turtle.onclick NOTE: It works when I click on the arrow head, but thats not what I want. I want to click some other position on the screen to

Turtle graphics - How do I control when the window closes?

阅读更多关于 Turtle graphics - How do I control when the window closes?

问题 I have a small python script which draws some turtle graphics. When my script has finished running, the turtle screen automatically closes, so to be able to see the graphics for a while I have to use time.sleep(5) at the end of the script to delay the closing. Is there any way I can make this more dynamic, i.e. tell python that I want to control the closing of the window myself? I don't mind if the script can't do anything else while waiting for my command, but I'd prefer if I didn't have to

Is there a way to save turtle's drawing as an animated GIF?

阅读更多关于 Is there a way to save turtle's drawing as an animated GIF?

问题 I like what the turtle module does in Python and I'd like to output the entire animation of it drawing the shape. Is there a way to do this? GIF/MP4/anything that shows the animation. Note, I know that an external screen recorder will do the job, but I'm looking for a way for the turtle module to do this itself. 回答1: Make an animated GIF from Python turtle using Preview on OSX 1) Start with a working program As obvious as that seems, don't be debugging your code while trying to generate the

问题 I have written a turtle program in python, but there are two problems. It goes way too slow for larger numbers, I was wonder how I can speed up turtle. It freezes after it finishes and when clicked on, says 'not responding' This is my code so far: import turtle #Takes user input to decide how many squares are needed f=int(input("How many squares do you want?")) c=int(input("What colour would you like? red = 1, blue = 2 and green =3")) n=int(input("What background colour would you like? red =
