Modern Python Cookbook - Second Edition

This is the code repository for Modern Python Cookbook - Second Edition, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

About the Book

This book comes with over 133 recipes on the latest version of Python 3.8, that will touch upon all necessary Python concepts related to data structures, OOP, functional, and statistical programming to get acquainted with nuances of Python syntax and how to effectively take advantage of it. By the end of this Python book, you will be equipped with the knowledge of testing, web services, configuration and application integration tips and tricks. You will be armed with the knowledge of creating applications with flexible logging, powerful configuration, and command-line options, automated unit tests, and good documentation.

All of the code is organized into folders. Each folder is numbered chapterwise Chapter_03 and further inside recipewise Ch03_r01.py, some execution is also shown in the example.txt file.

Installation and Setup

Install either Miniconda or Anaconda.
Create the book's environment.
```
conda create -n cookbook python=3.8
```
Note that python 3.8 is required. A few of the examples will not work with Python 3.7.
Activate the environment.
```
conda activate cookbook
```
Install the required components. This will download and install all of the packages listed in the requirements.txt file.
```
python -m pip install --requirement requirements.txt
```
Run the tox tool to test all of the modules.
```
tox
```
No Internet.
- tox (or tox -e py38,network) will run all tests.
- tox -e py38 will run the subset of tests that do not need an internet connection.
Windows.

The Chapter_05 examples make OS requests that work for Darwin and Linux, but are not designed to work for Windows. In this chapter's examples, also, you might need to use #doctest: +SKIP to skip over tests that are not relevant for your specific OS.
To run the Chapter 12 tests that require the proper SSL setup.
```
tox -e ssl
```

To run a specific example as a main program, be sure to set the PYTHONPATH environment variable.

PYTHONPATH=. python Chapter_13/ch13_r06.py data/ch13*.yaml

To run a number of main program demos, use the following tox environment

tox -e main
