Already updated my pip, still failed to add circle as a module

Question

1. I have been searching for different methods for using a class method to create circles. At first, I was able to print 'c1', however, after updating my python, it said is not defined which confuses me.

def __int__(x0, y0, r):
          self.x0 = x0
          self.y0 = y0
          self.r = r

    # create a unit circle centered at (0,0)
        c1 = Circle(0, 0, 1)
    
    # create a circle of radius 3 centered at (0,0)
        c2 = Circle(0, 0, 3)
    
    # create a unit circle centered at (2, 5)
        c3 = Circle(2, 5, 1)

    # create a circle of radius 3 centered at (4, 2)
        c4 = Circle(3, 4, 2)

    print (c1)
--------------------------------------------------------------

    from circle.Circle import move

    c1_xdelta = 4
    c1_ydelta = 5

    for i in range(1, 20):
        if i%10 == 0:
            c1.move(c1_xdelta, c1_ydelta)

    from circle.Circle import move
        c1_xdelta = 4
        c1_ydelta = 5

    for i in range(1, 20):
       if i%10 == 0:
           c1.move(c1_xdelta, c1_ydelta)

    from circle.Circle import move
         c1_xdelta = 4
         c1_ydelta = 5

    for i in range(1, 20):
       if i%10 == 0:
         c1.move(c1_xdelta, c1_ydelta)
---------------------------------------------------------------------------

Is there any method that I can solve it or any recommended websites for such programming functions? Thank you.
