Conventions used

There are several text conventions used throughout this book.

Code in text: Indicates code words in the text, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

# covid19_features.py
from Bio import SeqIO

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

>>> from Bio import SeqIO

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

>>> from Bio import SeqIO

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “In the Create the default IAM role pop-up window, select Any S3 bucket.”
