Unable to open idle3 in ubuntu

When I enter the idle3 command I get the following error:

Traceback (most recent call last):  File "/home/robin/anaconda3/bin/idle3", line 5, in <module>    main()  File "/home/robin/anaconda3/lib/python3.8/idlelib/pyshell.py", line 1477, in main    root = Tk(className="Idle")  File "/home/robin/anaconda3/lib/python3.8/tkinter/__init__.py", line 2261, in __init__    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)_tkinter.TclError: no display name and no $DISPLAY environment variable

What could be the reason for this? I am using ubuntu as WSL in windows-10
