Pyqt QtCore.QTimer() .timeout.connect(self.function) error [missing 1 required positional argument: 'Form']

Question

As part of a function inside a python script of a PyQt5 Gui i have the following code:

def link_info(self, Form):
    self.timer = QtCore.QTimer()
    self.timer.stop
    self.ip=self.lineEdit_ip.text()
    self.port=int(self.lineEdit_2.text())
    self.function(Form)
    print('here')
    self.timer.timeout.connect(self.function)
    self.timer.start(5000)

I am getting the error:

function() missing 1 required positional argument: 'Form'

When I change the code to:

self.timer.timeout.connect(self.function(Form))

I get the error:

argument 1 has unexpected type 'NoneType'

How can i solve this?

Thanks

You'll need to use either lambda: self.function(Form) or functools.partial(self.function, Form) to get a callable which doesn't require an argument, but still can be called at a later time by QTimer.
