Learning Python: Variables and primitive data types

Hey and welcome to my first blog post. In this one I'll introduce you to the programming language Python, but before we get into it, I'll want to give you a general idea of what programming is. What is programming? Programming is nothing else then giving your computer a set of instructions. Actually we're all doing it in some kind everyday without even knowing. Opening your Web browser or using a calculator, somehow you want your computer to execute these tasks. So you must be able to communicate in a certain language with your computer, but they can just handle 0's and 1's (Bits). So how is it even possible to understand a simple command like "5 + 5"? How should they know what the number 5 is or what a "+" is? The answer is, everything is encoded in a sequence of bits. For example "5" could be represented as "101" and let's say "+" is encoded as "000111", then "101 000111 101...

Learning Python: Functions and if-statements

Hey and welcome to my second blog on python programming. Today we're going to talk about functions and if-statements. In the last tutotial I forgot to mention, how to actually execute python code. There are two ways: using the Interpreter : open up your console and just type 'python' (each line of code gets immeditialy executed) save your code in a .py-file, open up your console and type 'python <filename.py>' Functions in Python Functions do we know already from math. We put some numbers in them and receive an output. Let's define a function called f(x) = x² and take 4 as input (argument). We get f(4) = 16 as output. Now in python: def f(x): return x**2 In the first line we have our function definition. ' def' is a keyword in python and it needs a function name with parentheses and a colon afterwards. In the parentheses we can put our argument variables. Line 2 is intended, shows another keyword ' return ' and the actual operat...
