So, a year and a half since my last post. Even if I kind of update my page to be a blog from the root, shame on me.
This blog post however is not something related to what I did in the previous ones. I promise someday I will continue with my Python to Scala tutorials, but for now you’ll have to settle with this.
Since I am a PhD Student in Natural Language Processing and a native speaker of the Spanish language, I like to do my research in this language. The problem is that Spanish, unlike English, doesn’t...
Following my series of tutorial of Scala for Python programmers, I’ll start to talk about something most Python programmers don’t usually pay attention to because the language doesn’t require it to do so.
I’m talking about data types. It’s not that Python doesn’t have types for its variables, but as it is a dynamically typed programming language, you usually don’t care about the type of the variable. At least not unless you try to add a number and a letter: you cannot add apple and oranges, naturally you cannot add strings and numbers (not at least without conversion first):
In general terms, however, Python won’t bother about the type you are giving to your variables: actually, you won’t be able to declare a type for them as Python will infer it. So, this is perfectly normal for a Python program:
This is the first post in a series in which I’ll try to give a nice insight for the Scala Language to a programmer with background in Python. I chose to do these posts since, at least when I started this series, the “Scala for people coming from Python” tutorial was a work in progress.
First of all I’ll state some of my background (in case you didn’t check my about page), in a kind of a disclaimer. There are people out there who are experts in Python. I’m not one of them. I only have a background of 4 years in this language, and only work with the 2.X version (started with 2.5 until 2.7). Never even try to learn Python 3. Also, there are experts on Scala as well, I’m not one of those either. In fact, my Scala knowledge is far from deep, I learned Scala at the end of last year and been using it since then (along with Python).

Once you know this, I’ll just say I have enough knowledge of both Scala and Python to get by. I’ve done some projects in Django and some projects in Play Framework, but nothing really impressive. The reason I’m doing this set of tutorials is because when I started to learn Scala I didn’t have one and many times I end up in Stackoverflow looking for how to do in Scala things I did in Python.
As every programmer trying to learn a new language, I think is suitable for me to start this professional blog with a Hello World. So, in this first blog post I say Hello World!
This is the first blog I’ve created that has relation with what I do for a living. The only other surviving blog is a personal one (and is in Spanish also).
The aim of this place is to write about Computer Sciences problems and solutions I came across to overcome them, most of them of course are programming ones.
As I said in my about page, I was for a long time a Python programmer, but now I turn myself into the world of Scala and it has so interesting I’ve practically abandoned my old time coding Python skills (of course, with Python, is never that hard to return).
I hope my posts will help you somehow.
