Introduction to Python Tales

Hello my friends, my name is Nelson Carrasquel, and perhaps as you I have the philosophy of coding for life, since 2013 when I started programming with Python (I have started before in 2008 with Delphi and some Visual Basic, but that is my dark past) my value as a Developer really increased due to the things that I found that could be possible with Python, now Python (with some Javascript) are the core languages for almost every challenge that I face in the programming world. I am a Chemical Engineer graduated from the UCV (Central University of Venezuela) in 2015, was working as an engineer for almost two years for an Automation and Control Systems Company, programming with LabVIEW almost all the time, but also I was tutoring as a part time job, helping students from all around the world (Not all the world but all the America) in their Python and Javascript assignments and projects; I found out that I really enjoy teaching and tutoring programming languages, and from that on I was kin…

Handling Relational Database with Python (Part I - Setting Database Up)

Hello my fellows Pythoneers in this new entry I’m going to talk about a cool topic, and that is handling SQL database systems with Python, but first let’s talks as usual about some background theory so we can put you in context.

So structurally speaking it would be something like this. Database -> Table -> Row Tables are organized as concerns in your applications, each table have a fixed  number of columns in which each column represent a feature of attribute of those elements that we want to save in each table. And finally every row is a unique entry. We can understand these co…

Python Free Books

Hello my friends in an earlier post I talked about some dive deep Python Books that you could purchase to start learning Python, you can check that entry in this link, and now I have decided to write this entry to give you a list of online and free Python books.


These books are supposed to be hosted documentation; they are written in restructured text (reStructuredText) and translated into beautiful HTML or PDF with a tool called Sphinx. This documentation format is supposed to be used for writing your own packages and modules documentation, but experts also use them to write practical books and tutorials of different languages and they can be uploaded and hosted for free in different online platforms, one of them is read the docs website.
