6.10 on my Mac Mojave 10.14.6
and looks like running tkinter crashed/ restarts my Mac
The question is already been asked (see the link below) Why tkinter fails on Mac
Does anyone know what version of python is compatible with tkinter
for those who are interested I just ran a simple code
from tkinter import *
window = Tk()
def printtheword():
print('Success!')
b1 = Button(window,text="Execute",command=km_to_miles)
b1.grid(row=0,column=0)
e1 = Entry(window)
e1.grid(row=0,column=1)
t1 = Text(window,height=1,width=20)
t1.grid(row=0,column=2)
window.mainloop()
