Python Combat Guide

A comprehensive manual about tricks, good practices and coding style for hands on Software Developer Managers and Developers

Python Combat Guide
Is a practical guide, to setup projects from zero, or to improve existing ones.

Across 365 pages DIN A4, in PDF format, provides comprehensive explanations with code samples, tips and trick, nice todo and don't-do-this.

Is a very practical guide, covering many aspects, talking superficially about many things interesting things to know like using Docker, Jenkins, Puppet, Infrastructure as code, Blue/green, canary deployment, git... and going in deep to some good practices, with a lot of source code samples.

Explain how to setup Unit Testing with pytest from the scratch, PyCharm and does some practical TDD with examples.

Make easy to use Virtual Environments and how to create your own PIP Packages.

What is it?
A very practical hands on manual for companies working with Python 3 (and moving from Python 2.7 to Python 3).

I explain my experience working in several actual projects, different sizes and teach good practices.

Like the title suggest is a Combat Guide: read it and start crushing it!.

Is the Master Class that your best friend working in a multinational will teach you to help to improve how you and your Team work.

Having in consideration Operations Engineers, SRE and SysAdmins, it explains how to move from Procedural code to OOP, and how and why to use Interfaces and Base classes (Parent) and children (subclasses).

I use practical examples, and compare Bash and Python for different scenarios, and I show pytest Unit Testing from the scratch.

Probably you'll love it if you know Java or PHP cause in 5 hours will enable you to write code in Python.

I also provide a very simple Flask Web Application, so you see how easy it is, a simple SQLITE3 example, a simple GUI TKinter LDAP application, Cron Jobs that send email, Sorting Data Structures using .sort(), sorted() and lambdas, Docker samples...

When possible instructions are provided for Ubuntu Linux, Mac Os X and Windows.

Price
Price is $5 USD, as minimum, and $20 suggested.

I decided to set the price to the minimum ($5), at least during covid, in order to help people that want to learn and improve. (this is not a manual for novices, but for people that actually know Python, SysAdmins, Architects and Managers)

Special Covid-19
I release this guide during coronavirus quarantine, in Ireland.

This is a technical guide, intended to serve to all level of Developers and to SDMs (SDM - Software Development Managers).

Also useful for Team Leads and Project Managers..

It is not a basic manual, however I want to give a chance to non-tech people to learn how to program in Python, so they can get a good life or in the case of the scientists and academics that lost their jobs in the universities and need to go back to the market. Many of them use tools like Jupyter Notebook with Python, so they only need a Master Class to empower them to work in modern projects, with Git, Unit Testing, nice good practices, Team work...

What is not?
A typical manual to learn Python for beginners.

If you're looking for this, this is not your book.

Is focused on writing CLI programs, Crons and does not cover Django.

It is not a manual to learn specific Python language features in deep. Does not cover Python 3.7, 3.8 or 3.9 new features as the code I write tries to work across many different versions of Python (and Servers running them). Does not cover Django.

Neither explain Architecture Patterns like Event Queues or Microservices. Or how to write API's, there are many books for that.

It just go for pointing the effective way to build CMD Line applications, Crons, use Dependency Injection, and Unit Testing in a very professional way.

Also cover certain common sense aspects for working in Team, good practices, and some Scaling tricks.

So basically allowing SRE, DevOps and Managers to improve the way they run Command Line Appications, Server side scripting, Server Monitoring...

Currently I don't cover Google Cloud Python Engine or Amazon AWS lambda with Python, although I have plans to do it.

I think you will learn many useful things, but if you buy it and you are not satisfied, please feel free to return it. When you buy it you have a period of time to return it, which at the moment of this writing is 10 days. I only had one return, and it was a professional editorial that wanted to print the book in the States. But honestly, I like to keep all the rights and to be able to communicate with you and to update the book often. ;)

Is the code in gitlab?
Yes, most of the code is in gitlab, so you can download and just run it.

However is better to follow the book, as there are some errors intended, in order to show what not to do, and without reading the book you'll not understand it.

Even if you didn't buy the book, feel free to download the source code in gitlab:
