# Vectors in Python

This guide provides an overview of a RhinoScriptSytntax Vector Geometry in Python.

## Vectors

Like 3-D points, 3-D vectors are also represented as zero-based, one-dimensional list that contain three numbers. These three number represent to the X, Y and Z coordinate values of the vector. Note, unlike points, vectors define magnitude (length) and direction, not position. A 3-D vector can be constructed in a number of different ways. For example,

vector1 = [1.0, 2.0, 3.0]


A point list can also be constructed one element at a time:

vector2 = []
vector2.append(1.0)
vector2.append(2.0)
vector2.append(5.0)


Vectors can also be created from two 3-D points using the VectorCreate method:

import rhinoscriptsyntax as rs

point1 = [1,2,3]
point2 = [4,6,7]
vector = rs.VectorCreate(point2, point1)

print vector


Rhinoscriptsyntax contains a number of methods to manipulate vectors. See Points and Vectors for details.
