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). ... Within the list we can change one of the elements with a new value. In this case we will substitute the second element on the list ...

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.

Later we pass this list to numpy.histogram function to do binning: (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.

The numpy.array function is used to create a NumPy array. Here we just have to pass in a list of lists, it will automatically generate a NumPy array with the same number of rows and columns. Because for easy computation, we want all the elements in the array to be float elements, so, we’ll leave off the header row and column, which contains ...
