How to use self parameter, @staticmethod keyword inside a class and its methods

I have a python class which has multiple methods. I have defined my methods via @staticmethod instance and I want to call other methods of my class from inside my main function(main_function). I think I need self parameter for calling my other functions from my main function and I want to pass this parameter to my main_function when I create an instance of my class.

class myclass:
  @staticmethod
  def function1(param1)
      print "function1"
  @staticmethod
  def main_function(self, param1)
     function1(param1)

my_object = myclass()
my_object.main_function(param1)

I got this error:

TypeError: main_function() takes exactly 2 arguments (1 given)

The problem is that I have not self parameter when I create my instance. I tried to remove @staticmethod keyword from my method definition and remove all self parameter using, but this does not work.
