I don't have any error messages at console, but have this message "Oops, try again. It looks like you didn't print "(1,2,3)"" My code DOES print "(1,2,3)" in console. I don't see anything wrong in my code.
Pass me to next stage
class Point3D(object): def __init__(self,x,y,z): self.x=x self.y=y self.z=z def __repr__(self): return "(%d,%d,%d)"%(self.x,self.y,self.z) my_point=Point3D(1,2,3) print my_point
