Wouldn't it be simpler to just do:

curve = [(x0, y0), (x1, y1), ... (xn, yn)]

It's common to simply use a tuple in Python where structs are
used in other languages. Or use complex numbers if you don't like
to access with [0] for x coordinate and [1] for y coordinate.

 >>> coord0 = complex(1.123, 4.5)
 >>> coord0.real
1.123
 >>> coord0.imag
4.5

Then you have the arithetic you need if you for instance want to
see the difference between to coords.

 >>> coord1 = complex(1.623, 5.5)
 >>> diff = coord1-coord0
 >>> diff.real
0.5
 >>> diff.imag
1.0
