I An array appears to be very similar to a list but an array can keep only elements of the same type (arrays are more eﬃcient to store) I Vectors and matrices are all called ”arrays” in NumPy. I To create a Vector (one dimensional array) we do: 1 >>> import numpyasnp 2 >>>x=np.array([0 , 0.5 , 1 , 1.5]) 3 [0 , 0.5 , 1 , 1.5]

Jun 17, 2014 · An array can be created from a list: >>> a = np.array([1, 4, 5, 8], float) >>> a array([ 1., 4., 5., 8.]) >>> type(a) Here, the function array takes two arguments: the list to be converted into the array and the type of each member of the list. Array elements are accessed, sliced, and manipulated just like lists: >>> a[:2 ...
