Instantiating a Canvas in Python : tkinter.TclError: no display name and no $DISPLAY environment variable
Very new to python, just trying to create a Canvas in python using tkinter:
from tkinter import *
top = Tk()
w = Canvas (top , height = 300, width = 300)
Yields error:
_tkinter.TclError: no display name and no $DISPLAY environment variable
Most of what I saw regarding this issue had to do with running code on a remote machine and not having a place to display the output. I was running this on the online compiler:
https://repl.it/repls/MintyHumongousParentheses
Any insight into this error is appreciated, thank you!

If where you are executing the code does not contain a display you will not be able to run tkinter. Your online compiler will ending having the same issue as well. Unless it contains some kind of virtual display (the console window does not count).

The tkinter package is a thin object-oriented layer on top of Tcl/Tk. The problem is Tcl can't find the virtual display.
As stovfl pointed out your problem is the online python editor, I don't know witch one you are using, but repl.it is compatible with remi.gui, see example: https://repl.it/@amasad/tictactoe.
I tested your code locally and it didn't work, so I made a few changes:
from tkinter import *
top = Tk()
w = Canvas(top, width=300, height=300)
w.pack()
top.mainloop()
