NameError: name 'MysubClass' is not defined

class Displayer:
    def display(self,message):
      print(message)

class loggermixin:
def log(self,message,filename="logfile.txt"):
    f.write(message)

    def display(self,message):
      super().divplay(message)
      self.log(message)

class Mysubclass(loggermixin,Displayer):
    def log(self,message):
      super().log(message,filename="subclasslog.txt")

subclass=MysubClass()
subclass.display("this is a test.")
