Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, path names, dummy URLs, user input, and Twitter handles are shown as follows: "Let's generate a large number of events of a Bernoulli distribution using np and graph the tendency of this distribution."

A block of code is set as follows:

def mean(sampleset):  #Definition header for the mean function 
        total=0 
        for element in sampleset: 
            total=total+element 
        return total/len(sampleset)         

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In order to download new modules, we will go to Files | Settings | Project Name | Project Interpreter."
