Why Does Pycharm Raise A Warning When Using @property Here?

In tutorials I have seen two types of instance attribute naming for the purpose of using @property. Here is code showing examples of both. They also seem to work differently. class

Solution 1:

It seems to be a bug in PyCharm: https://youtrack.jetbrains.com/issue/PY-25263.

A temporary solution I found was to add self._x = None in the __init__. So the code would be:

classA:
    def__init__(self, x):
        self._x = None
        self.x = x

    @propertydefx(self):
        return self._x

    @x.setterdefx(self, x):
        if x > 1000:
            self._x = 1000else:
            self._x = x


a = A(9999)
print(a.x)  # -> 1000
