Bug Report
mypy is thorwing errors at properties that are properly defined (unless I am mistaken).
Here is my code:
from fs.sshfs import SSHFS
class SMS:
_USER_DEFAULT: str = "xxx"
_PASSWORD_DEFAULT: str = "xxx"
_PORT_DEFAULT: int = 22
def __init__(
self,
host: str,
user: str = _USER_DEFAULT,
password: str = _PASSWORD_DEFAULT,
port: int = _PORT_DEFAULT,
):
self._host: str = ""
self._user: str = ""
self._password: str = ""
self._port: int = 0
self.host = host
self.user = user
self.password = password
self.port = port
@property
def sshfs(self) -> SSHFS:
return SSHFS(
host=self.host, user=self.user, passwd=self.password, port=self.port
)
@property
def host(self) -> str:
return self._host
@property
def user(self) -> str:
return self._user
@property
def password(self) -> str:
return self._password
@property
def port(self) -> int:
return self._port
@host.setter
def host(self, host: str) -> None:
if not isinstance(host, str):
raise TypeError("Host must be a string!")
self._host = host

def user(self, user: str) -> None:
if not isinstance(user, str):
raise TypeError("User should be a string!")
self._user = user

self._password = password
@port.setter
def port(self, port: int) -> None:
if not isinstance(port, int) or port < 21:
raise TypeError("Port number must be an integer and above 20!")
self._port = portTo Reproduce
