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: "You should be then presented with a .jar file, which you can save."

A block of code is set as follows:

def add_one(n):
    return n + 1


def foo(func, n):
    return func(n)


foo(add_one, 2)

Any command-line input or output is written as follows:

pip install ipython[all]

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: "What I've tried to do is put in the name of the action being done so that you can take a look in your Keymap (by navigating to File | Settings…)."
