A vector is formally defined as an element of a vector space. In the commonly encountered vector space R^n (i.e., Euclidean n-space), a vector is given by n coordinates and can be specified as (A_1,A_2,...,A_n). Vectors are sometimes referred to by the number of coordinates they have, so a 2-dimensional vector (x_1,x_2) is often called a two-vector, an n-dimensional vector is often called an n-vector, and so on.

I usually plug in a garden hose to my shower, turn on the water with the hose in the tank, pull off the hose from the shower and go do something else for an hour.
Works fine, should you ever get into a situation where your "Python" acts up again
