Get started learning Python with this tutorial from our archives.

The cool thing about Linux and FOSS is also an aggravating thing, which is that sometimes there’s too much of a good thing. There is such an abundance of goodies that it can be overwhelming. So I am here to help you decide which programming language you should learn next, and that is Python. Oh, yes, it is.

Why Python? I like it because it is clean and straightforward. It’s a great introduction to object-oriented languages. The Python world is beginner-friendly and, as a general-purpose language, Python can be used for all sorts of things: quick simple scripts, games, Web development, Raspberry Pi — anything you want. It is also in demand by employers if you’re thinking of a career.

There are numerous excellent Python books and tons of online documentation. I want to show off Python’s coolness for beginners so you will get excited and go “Yes! I too must love Python!”

But what about all the other languages? Don’t worry, they won’t get lonesome, and everything you learn in Python is applicable to many other languages as well.

What Stuff Means

I think most of us learn terminology better with hands-on exercises, but there are four things to know from the start.

The first is Python is strongly typed. As you study Python, you will see this repeated a gazillion times. What does this even mean? Who uses a typewriter? Fortunately, it has nothing to do with typewriters, but rather with how Python handles data types. All computer programs are made of two things: data, and operating on that data. Data comes in different types, and the types determine how your programming language will handle them. Data types include characters or strings, which are literal numbers and letters, like names and addresses; integers and floating point numbers that are used in calculations; Boolean values (true/false); and arrays, which are lists of data of all the same data types.

Python enforces data types and relies on you to define them. Weakly typed languages decide for themselves what your data types are, so the data type can change depending on context.

For example, most any programming language will add the integers 1 + 2 + 3. A weakly typed language may also let you add integers and text strings, for example 5 + helloworld. If you try to do this in Python, your code will fail and you will get an error message. Weakly typed languages don’t do this randomly; this is a feature intended to add speed and flexibility by not requiring you to define your data types.

However, weak typing can lead to strange errors. One of the most common errors involves converting strings of numbers to integers when you really want them to be a literal string, like 221B Baker Street, 10,000 Maniacs, or 23andMe. In my modest opinion, it is better to learn the discipline and structure of a strongly typed language, and then try out weakly typed languages after you have experience and good grounding in the basics.

The second thing to know is what the heck is object oriented programming (OOP)? An object is a clump of data and procedures grouped into a single reusable entity. If you were coding a car racing game you might have a car object, an obstacle object, and a driver object. So, you say, objects are just like functions, right? Yes. If you already understand how to organize code into properly grouped functions and variables, then you already understand OOP. There are finer points to OOP such as classes, inheritance, and polymorphism; again, if you think in terms of sensible organization these things are easier to understand.

Third, white space has meaning in Python. You have to get your white spaces right or your code won’t work.

Fourth, Python is an interpreted language. You don’t have to compile and link your Python programs. If you’re experienced with the Bash shell, then you already know about interpreted languages, how fast they are to code in, and how you can test out your programs interactively before writing them into a script.

The downside to interpreted languages is the overhead of the interpreter. Usually, programs written in compiled languages run faster. However, you can link your Python programs to functions written in many other languages, including C/C++, Lisp, Fortran, Java, and Perl, and many more so you can mix and match to get the results you want.

Try It

Python is included in most Linux distributions, and usually the python package installs the base components and Python command interpreter. The text in bold is what you type.

$ python

Python 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> help() Welcome to Python 2.7! This is the online help utility. If this is your first time using Python, you should definitely check out

the tutorial on the Internet at http://docs.python.org/2.7/tutorial/. Enter the name of any module, keyword, or topic to get help on writing

Python programs and using Python modules. To quit this help utility and

return to the interpreter, just type "quit". To get a list of available modules, keywords, or topics, type "modules", "keywords", or "topics". Each module also comes with a one-line summary

of what it does; to list the modules whose summaries contain a given word

such as "spam", type "modules spam". help> topics Here is a list of available topics. Enter any topic name to get more help. ASSERTION DEBUGGING LITERALS SEQUENCEMETHODS2

[...]

help> quit

Of course we must do the traditional Hello World! Strings must be enclosed in single or double quotes.

>>> 'Hello, world!' 'Hello, world!'

>>> hell = "Hello, world!"

>>> hell 'Hello, world!'

Now create the simplest possible Python script, save it as hello.py, and run it from your normal Linux shell:

#!/usr/bin/python print "Hello World!"; carla@studio:~$ python hello.py

Hello World!

Let’s go back to the Python interpreter and play with data types.

>>> 2 + 2

4

>>> 2 + foo

Traceback (most recent call last): File "", line 1, in NameError: name 'foo' is not defined

>>> foo = 5

>>> 2 + foo

7

Now try a short interactive script. It asks you to input your age, responds according to the age you type, and checks if your response is in the correct data type. This is a great little script to tweak in different ways. For example, you could limit the acceptable age range, limit the number of incorrect tries, and get creative with your responses. Note that raw_input is for Python 2.x, and 3.x uses input.

Watch your indentation; the indented lines must be four spaces. If you are using a proper code editor, it should take care of this for you.

#!/usr/bin/python while True: try: age = int(raw_input("Please enter your age: ")) except ValueError: print("I'm so very sorry, that does not compute. Please try again.") continue else: break

if age >= 18: print("Very good, you are old enough to know better, but not too old to do it anyway.")

else: print("Sorry, come back when you're 18 and try again.")

Modules and Learning

There are a great number of Python modules, and you can learn to write your own. The key to writing good Python programs and making them do what you want is learning where to find modules. Start at Python.org because of the abundant documentation and good organization. Plan to spend a lot of time here, because it contains the best and authoritative information. It even has an interactive shell you can practice with.

Yesterday we reported on an unofficial Fortnite event in the UK (in the fair city of Norwich, to be exact) and it seems that the weekend woes, bad press and refund requests aren’t the last of the headaches for the organisers.

According to Eurogamer, Epic Games has taken note of the hubbub surrounding the disorganised event and is taking legal action to prevent any further events.

According to Norwich Evening News, Shaun Lord, head of the snappily named Exciting Events company responsible for ‘Fortnite Live’, had planned further events in both Spalding and Newark, hoping that the festival would gain traction. However, that seemed to be unlikely after yesterday’s news stories, and impossible now Epic’s legal eagles have decended.

“We want to keep this going because we are a family business,” Lord said, “we want to do this for the kids and this is for the kids who love the game of Fortnite.”

We admit to feeling just a little sorry for the organisers. Their brazen use of Fortnite assets to promote the event notwithstanding, it’s a shame that their ambition outstripped their abilities to put on a decent show for fans. For all his missteps, it’s hard to disagree when Lord bristles at comparisons to Fyre Festival.

“To relate to that was a bit harsh. People are entitled to their own opinion and we can’t stop that.”

The post Announcing new standards-aligned math lessons appeared first on Minecraft: Education Edition.

Coming from Devespresso Games, the Korean studio behind The Coma: Recut, their latest game is planned for a summer release on Switch and other consoles following a PC launch in April.

Vambrace: Cold Soul is a hand-illustrated ‘roguelite’ adventure set in the city of Icenaire. The city is populated by a host of unusual survivors and it’s your job as Evelia Lyric – the only human who can enter the city – to form a party from the characters you meet and venture out on expeditions.

It looks to be a narrative-rich adventure game involving crafting and battling. You’re fighting against the King of Shades who has cursed the city (hence the permanent chilliness, although what do you expect if you call your city Icenaire?) and created an army of undead Wraiths to terrorise all who remain. All sounds a little bit Game of Thrones…

It certainly looks nice. Here are a few highlighted features from the official blurb:

Features
· Embark on an epic fanasy-adventure spanning 7 intriguing chapters
· Complete sub-quests to unlock up to 26 new, thematic character skins
· Assemble your party from 5 races and 10 unique classes of recruits
· Craft items and armour from precious materials gathered on your trips that will unlock new skills and enhance stats
· Make crucial decisions – one wrong turn can seal your party’s fate
· Prepare well or condemn your comrades to permanent death
· Find codex pages to expand upon the world’s history and mythical lore

Like the look of this or have you had your fill of roguelike adventures? Think you can survive the White Walke…, sorry, the Wraiths and take down the King of Shades? Share your thoughts in the usual place.

Similar to the previously unearthed prototype designs for Pokémon Gold & Silver, further discoveries seem to have been made about original Pokémon Red & Blue monsters. A fresh batch of prototype assets has been published by Helix Chamber which includes clearer, better-quality versions of previously uncovered goodies.

The whole story surrounding the anonymous origins of these prototypes should have keen pokéstorians on their guard, as it did Helix Chamber when the fan group was first approached, but the authenticity of the sprites has been independently verified against other data – all these assets appear to be legitimate.

We already knew from previous documentation that an earlier name for the gotta catch ’em all game was ‘Capsule Monsters’, but now we get a much clearer picture of a prototype title screen which shows an early pokéball as the ‘O’ in ‘Monsters’.

Another picture shows an early version of what appears to be a Rhydon standing over the revised ‘Pocket Monsters’ logo:

There’s plenty more to check out: an entire folder’s worth of assets for fans to download and examine in detail, including an early Blastoise named ‘Totartle’ and analysis of the fabled Missingno – the well-known glitch that’s easily found in-game – plus a whole sheet of early designs.

Head over to Helix Chamber for the exhaustive lowdown.

Think Pokémon would have taken over the world under a different guise? Are any of these prototype ‘mon more interesting than Metapod? Drop us a line in the comments…
