Conventions used

There are a number of 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: “Execute python --version from the command line.”

A block of code is set as follows:

from flask import Flask
app = Flask(__name__)
@app.route('/')

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

from flask import Flask
app = Flask(__name__)
@app.route('/')

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

wget https://raw.githubusercontent.com/PacktPublishing/Python-Essentials-for-AWS-Cloud-Developers/main/fileprocessor.py

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: “Click Instances on the left side, and then click Launch Instances.”
