Processing.py - Unknown Error On Class Definition

I have no idea how to fix this error. Maybe there's an open parenthesis or quotation mark somewhere before this line? What is wrong with this code? Class Ribbon: # I got an error

Solution 1:

Here is your problem:

Class Ribbon (object): 
      def__init__(self, xpos, ypos, m, g):
      self.x=xpos
      self.y=ypos
      self.mass=m
      self.gravity=g

also remember that other def must be indented properly as well
