use arcpy to describe a curve

[CarlSunderman]

Is it possible to use arcpy to give the properties of a curve?

To answer my own questions

def calculateRadius(x1,y1,x2,y2): 
    radius = (( x2 - x1 )^2 + ( y2 - y1 )^2)^0.5
    return radius 
print calculateRadius(x1, y1, x2, y2)

If you're using python, I think you mean:

def calculateRadius(x1,y1,x2,y2): 
   radius = (( x2 - x1 )**2 + ( y2 - y1 )**2)**0.5 
   return radius 
print calculateRadius(x1, y1, x2, y2)
