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)
app.master.title("Twitter votes")
app.master.geometry("400x700+100+100")
app.mainloop()
Any command-line input or output is written as follows:
python app.py --hashtags debian ubuntu arch
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "It says, Logged as with your username, and right after it there is a logout link. Give it a go, and click on the link Log off"
Warnings or important notes appear like this.
Tips and tricks appear like this.
