QRadioButton - Qt for Python

A is an option button that can be switched on (checked) or off (unchecked). Radio buttons typically present the user with a "one of many" choice. In a group of radio buttons, only one radio button at a time can be checked; if the user selects another button, the previously selected button is switched off.
