I decide to open a new tkinter window, but when i opened it and i tried to hit enter to input new commands to create a canvas in the new window, the enter key would not function unless i closed the window. e.g.:

>>> from tkinter import *
>>> tk = Tk()
>>> mainloop()

[this opens a new window titled "tk", but i cant hit enter to enter some more commands]

Ubuntu 20.04.1, and the IDLE i mentioned is python 3.8 and bpython 0.18
