Share 'AddCircle (python)'

hi @ll im trying to learn a little of python... for i in range(x):    print(i)        pt = (i, math.cos(i), 0)    circle = rs.AddCircle(pt,i+1)    circles.append(circle)    a = circles    i recognizedthat if i only input i for the radius , skript fails. i assume this is because of 0 is not ok for radius... how can i trick out this ? thank you !
