Hiding your actual variable behind a property is a nice trick to achieve what you wish for:
def fset(self, value):
self._my_var = value <<<<<<<<<<<<<<<<<<<<<
my_var = property(**_())
The rest of your code does not need to be touched in any way and you would then put a breakpoint at the line marked with <<<<<<
By putting a breakpoint in the getter, you can even stop every time self.my_var has its value read by user-code.
