Python Programming Blueprints

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This method will call the method exec of the Runner to execute the function that performs the requests to the Twitter API."

A block of code is set as follows:

def set_header(self):    title = Label(self,                  text='Voting for hasthags',                  font=("Helvetica", 24),                  height=4)    title.pack()

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

def start_app(args):    root = Tk() app = Application(hashtags=args.hashtags, master=root) ...
