The numpy function array creates a new array from any data structure with array like behavior (other ndarrays, lists, sets, etc.) Read the docs! Creating an ndarray from a list does not change the list. Often combined with a reshape() call to create a multi-dimensional array.

2D arrays • So far, we have been working with one dimensional arrays (e.g. array([1,2,3,4,5,…]) • With “matching” 1D arrays for x and y we can plot 2D data- such as position vs time. Each “data point” contains two pieces of information: x, and y (or time and position). • A 2D array allows us to plot 3D data points- …
