Description
Point is a pure Python class for
representing points on a plane. It is equivalent to the C++
Coord
class. The reason for having two classes is that there are
situations in which it's desirable to avoid the overhead of
calling C++ functions from Python, and in which the extra
memory required to store a Python object is not important.
Methods
__getitem__(i), __setitem__(i, val)
A single component can be extracted with
__getitem__ and set with
__setitem__. point[0]
is the x component and point[1] is the y
component.
__mul__, __add__, etc.
The standard arithmetic operators are defined for
Points. They can be added or
subtracted from one another, and multiplied or divided by
integers or floating point numbers. Multiplying two
Points produces their dot product.
