Weird question marks getting entered in tkinter entry when function keys are pressed-CodePudding

I am coding an application that sends entries to a database. I use tkinter.Entry for getting user input. When I press the function keys a weird question mark appears in the entry and python treats it as a character on my mac. While I used it on windows I didn't get the question marks. I also restarted my mac but it doesn't help.

I found a workaround for it.

Create a function that returns "break" when function keys are pressed.


 def validate(event):
     keys = ['F1', 'F2', 'F3', 'F4', 'F5', 'F6', 'F7', 'F8', 'F9', 'F10', 'F11', 'F12']
     for i in keys:
         if i == event.keysym:
             return 'break'

Now bind the entries to the validate function

sample_entry.bind('<KeyPress>', validate)

This skips the KeyPress when the function keys are pressed.
