TheNumPymodule also has three functions available to achieve this task and generate the required number of random integers and store them in a numpy array. These functions arenumpy.random.randint(),numpy.random.choice(), andnumpy.random.uniform(). The following code shows how to use these func...

Using the numpy.random.uniform() function This function is similar to the random.uniform() function contained within the general random module, with the only difference being that the result is returned and stored in a NumPy array. The following code uses the numpy.random.uniform() function to...
