Here, we use NumPy which is a general-purpose array-processing package in python. To set the x – axis values, we use np.arange() method in which first two arguments are for range and third one for step-wise increment. The result is a numpy array. To get corresponding y-axis values, we simply use predefined np.sin() method on the numpy array.

Just as a for loop is a way to do operations many times, a list is a way to store many values. Unlike NumPy arrays, lists are built into the language (so we don’t have to load a library to use them).

With NumPy, we can easily combine multiple arrays into a single unified array. To perform this task, we can use numpy.vstack to vertically stack multiple arrays. Consider this in this way the second arrays’ items are being added as new rows to the first array.

First we bin array of values using numpy functionality: (n, bins) = numpy.histogram(volList, bins=10) The return values are two numpy arrays: n which specifies center of the bin (we plot it on x axis) and bins which determines stores counts for a given bin.

Array indices start at . 0, not . 1. Use low:high to specify a slice that includes the indices from low to high-1. All the indexing and slicing that works on arrays also works on strings. Use # some kind of explanation to add comments to programs. Use numpy.mean(array), numpy.max(array), and numpy.min(array) to calculate simple statistics.

Numpy – this library is for turning images into an array which can then be put through the model to retrieve a prediction. The model used in the training script (Appedix 6.1) is designed after the most successful machine learning algorithm from assignment 1.
