Numpy provides several built-in functions to create and work with arrays from scratch. An array can be created using the following functions: ndarray(shape, type):Creates an array of the given shape with random numbers array(array_object):Creates an array of the given shape from the list or...

So, first, we must import numpy as np. We then create a variable named randnums and set it equal to, np.random.randint(1,101,5) This produces an array of 5 numbers in which we can select from integers 1 to 100. 1 is inclusive and 101 is exclusive, so the possible ...
