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, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The next lines of code reads the link and assigns it to the to the BeautifulSoup function."

A block of code is set as follows:

for row in reader: 
         if (row['Denomination']) == 'Penny': 
            if int(row['Coin-in'])<2000: 
                x += int(row['Coin-in']) 
            row_count += 1

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

row_count = 0 
     aver_coin_in = 0.0 
     x = 0.0 
     y = 999 
     z = 0.0

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."
