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: "As you can see, pi is a float, name is a string, age is an integer, and sky_is_blue is a Boolean."

A block of code is set as follows:

import pandas as pd

for word in 'Hello Word!'.split():
    print(word)

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

pi = 3.14159265359    # Decimal
name = 'Philipp'      # Text
age = 31              # Integer
sky_is_blue = True    # Boolean

Often code will be shown as a print of an interactive console, with both code and the output being mixed. In this case, all input code lines will start with a triple "greater than" sign. Lines with no such sign represent the output:

>>> import pandas as pd
>>> for word in 'Hello Word!'.split():
>>>     print(word)

Hello
Word

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

> conda install <mypackage>
> conda install -c <mychannel> <mypackage>

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: "Just use the Clone or download button on the right-hand side (1), and select Download ZIP (2)."
