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: "By using the to_bokehmethod, any chart and plot from other packages can be easily ported into Bokeh."

A block of code is set as follows:

File: bottle1.py
from bottle import route, run, template
port = 9099
@route('/personal/<name>')
def homepage(name):
return template('Hi <b>{{name}}</b>!', name=name)
print("Try going to http://localhost:{}/personal/Tom".format(port))
print("Try going to http://localhost:{}/personal/Carl".format(port))
run(host='localhost', port=port)

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

In: import numpy as np
from bokeh.plotting import figure, output_file, show
x = np.linspace(0, 5, 50)
y_cos = np.cos(x)
output_file("cosine.html")
p = figure()
p.line(x, y_cos, line_width=2)
show(p)

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: "Once the Jupyter instance has opened in the browser, click on the New button."
