    It's hard to tell for sure with the broken formatting, but it looks like you are trying to call the *method* ``getstep`` as a *global function*. – MisterMiyagi May 21 '21 at 11:01
  • sry! I am new to forum . under a class random_move , I created two functions and I call a function from another one to request a list value. after that I import the class in a separate file and when I call the function from there, nameError was thrown into the screen – ravi May 21 '21 at 11:05

try it;

def track(self):
        self.xv= self.getstep()
        self.yv= self.getstep()

You have to call the method of the class via the object from the class or via the class itself passing an object of that class. In your case, to call track method, you should call self.getstep() or random_move.getstep(an_obj_of_the_class)
