Calculate circumference of an ellipse in python (both exact and approximate approaches)

#For the best exact circumference, use EllipseCircumAdlaj2012
#
#For good approximations that are faster to compute, see EllipseCircumRamanujan2ndApprox and EllipseCircumJacobsenWaadeland1985

#Incidentally, scipy has a function to exactly calculate it:
# C = 4.0*a*special.ellipe(e*e)
