Python conversion between coordinates

Question

Are there functions for conversion between different coordinate systems?

For example, Matlab has [rho,phi] = cart2pol(x,y) for conversion from cartesian

Answer 1

There is a better way to write polar(), here it is:

def polar(x,y):
  `returns r, theta(degrees)`
  return math.hypot(x,y),math.degrees(math.atan2(y,x))
