python - Error when attempting to call function from button in wxpython -

as beginner in wxpthon, i'm creating simple login script creates 2 buttons: 1 open window user create account, , 1 them register account. relevant code is:

 yesbutton = wx.button(panel, label="yes,  wish log in", pos=(50,150), size=(150,60))     self.bind(wx.evt_button, login.login(login), yesbutton)    nobutton = wx.button(panel, label="no,  wish register", pos=(270,150), size=(150,60))     self.bind(wx.evt_button, register.register(register), nobutton)   class login:       def login(self):         print("login")   class register:      def register(self):         print("register") 

however when run code get:

typeerror: unbound method login() must called login instance first argument (got classobj instance instead)

i've looked lot answer, can't make solutions work. in advance.

your functions login.login() , register.register() take no arguments, you're passing login , register classes them. second line should instead be:

self.bind(wx.evt_button, login.login, yesbutton) 

you don't need parentheses after login.login in case since it's within bind function. adjust other binding.

edit: need instantiate login object , register object before calling classes. unfortunately don't have access wxpython @ moment , can't test it, try this:

edit 2: pass event function, make sure functions calling account this.

yesbutton = wx.button(panel, label="yes,  wish log in", pos=(50,150), size=(150,60)) log = login() self.bind(wx.evt_button, log.login, yesbutton)   nobutton = wx.button(panel, label="no,  wish register", pos=(270,150), size=(150,60)) reg = register() self.bind(wx.evt_button, reg.register, nobutton)   class login:      def login(self, evt):         print("login")  class register:      def register(self, evt):         print("register")
