How to uncheck all checkboxes when one checkbox is checked in PyQt5? [duplicate]

There are 04 checkboxes. When a user checks one checkbox I want the other checkboxes to uncheck (if the user might have checked multiple ones) so that the checkbox the user checked will only remain checked. I tried to do this manually but it's not giving me what I have mentioned above. Any suggestions?
