My turtle module does not work in IDE. Can anyone help me?
Code:
import turtle
t = turtle.pen()
I wrote this code to make the turtle module open its app, but it didn't happen.
You have to add turtle.mainloop() or turtle.done() at the last of the file.
Starts event loop - calling Tkinter’s mainloop function. Must be the last statement in a turtle graphics program. Must not be used if a script is run from within IDLE in -n mode (No subprocess) - for interactive use of turtle graphics.
You can read turtle document for more details.

import turtle
fondo = turtle.Screen()
fondo.setup(width=500, height=500, startx=750, starty=300)
fondo.bgcolor("blue")
There's no TypeError or NameError in my project, so it's rare that this is happening. I'm using Pycharm for this project. Thank you
it work fine for me I run the script on my phone and it executed with no error. Could you check if you have installed a python compiler, cuz pycharm is just an ide.
You need compiler to run high level programming languages eg python, c++, java but you can run assembly on any device, c programming languages can run on windows also.
It probably does appear, but very quickly closes again. You didn't transfer control to the event handler so the program started and then immediately quit. Add a mainloop() at the end to transfer control:
import turtle
fondo = turtle.Screen()
fondo.setup(width=500, height=500, startx=750, starty=300)
fondo.bgcolor("blue")
# the rest of your code goes here
fondo.mainloop()
This is true for standard Python/turtle, under PyCharm, things might work differently.
I've seen python turtle programs use turtle.done(), turtle.mainloop() and turtle.exitonclick() apparently interchangeably. The docs give an example where they just use done() (which would be turtle.done() with import turtle.
Is there a reason to ever use anything but turtle.done(), which is my preferred command?
The short answer is that turtle.done() is an alias for turtle.mainloop() so the two are identical. The turtle.exitonclick() does what turtle.mainloop() does, but adds an event handler (the program exits when you click anywhere on the window.)

There is some subtlety in choice when moving between Python 2 and Python 3 as some of these change from functions to methods.
I've been trying to work through some beginner python turtle graphics turtorials in python 3.7 on Mac OS X El Capitan.
One of the things that seems annoying is that the turtle graphics window is opening up underneath the other windows.
I don't know if there is something wrong with my configuration, or whether it is typical of turtle graphics, but it would be nice if there an easy way to bring the window to the foreground. I have searched and found out that turtle graphics is based on tkinter, and found a couple of post on bringing tkinter windows to thr foreground.
I was able to get the following code to work with IDLE, but it doesn't work when running the program from the terminal.
import turtle
# works in IDLE, but not in OS X terminal
root = turtle.getscreen()._root
root.attributes("-topmost", true)
turtle.forward(100)
turelt.left(120)
I have tried looking through the turtle graphics documentation, but I didn't find any commands to bring a window to the foreground, and I am not fond of the idea of having to do a deep read through tkinter documentation just to be able to run a beginner turtle graphics tutorial.
That being said, knowing the right commands to get a tkinter-able reference to the turtle window, and knowing the correct tkinter commands would seem like an acceptable workaround.
Are there any basic turtle commands to bring the window to the foreground, or is there a way to get a reference to the root tkinter window in order to bring it to ther foreground??
Thanks in advance for any help or suggestions!!
Sincerely,

I am using Visual Studio Code as my IDE and I am a bit of a beginner with Python so I decided to try out the turtle library built into Python to learn some of the syntax. However, when I tried running just a simple script to see if it would work, the window flashed open for less than a second then closed. I have tried using different extensions and re-downloading the python extension for VS Code. This is my code I'm trying to run:
import turtle
geoff = turtle.Turtle()
geoff.forward(100)
Please help as I really can't figure out why the window won't stay open. Thanks!
The screen flashed on and then closed because when the application is done, Python exits and thus so does the screen. This has nothing to do with VS Code or the Python extension and simply how applications work.
Probably the easiest way to keep the window open is add the following line at the very end:
input("Press any key to exit ...")
That way Python won't exit until you press a key in the terminal.
The easiest solution is to add the following line in your V.S. Code:-
turtle.done()
This would prevent the window (Python Turtle Graphics) from closing after running the code:)
You can use exitonclick() to avoid the window from shutting down.
import turtle
window = turtle.Screen()
geoff = turtle.Turtle()
geoff.forward(100)
window.exitonclick()
This way, the graphics window will shut only after you click.
You can create a canvas into turtle like a blank space to draw on. Use this code just to import the module an hold on the graphic window open -Pen It will work with Visual Studio Code, Spyder or Python IDLE
import turtle
window = turtle.Screen()
geoff = turtle.Turtle()
t = turtle.Pen()
window.exitonclick()
I want to use an input parameter in my Python code, but instead of being asked in the Python editor toolbox, the user should be prompted in the Python Turtle Graphics window. I believe that this should be done by built-in write(), but I have no idea how to implement it.
"Write" is used for the turtle to write something in the window. You can not currently have an input in the turtle window, unless you code it all yourself.
