Conventions used

Here are the text conventions used throughout this book.

Code in text: 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 contains two basic functions: add() and subtract().”

A block of code is set as follows:

def add(a, b):
    return a + b
def subtract(a, b):
    return a – b

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “This process, known as unsupervised learning, does not require labeled data but instead relies on the patterns inherent in the text itself.”
