Object-Oriented Programming (OOP)

Now we arrived at object-oriented programming. This has (had) its hype where every language was designed around objects and Python developer Guido van Rossum thought “Why not?” and added classes to support object-oriented development. Some python evangelists think this was a bad decision, some think it was a good approach… This article is an excerpt […]

Guess the number — The return

We have seen this example previously. There I included a lot of loops to handle user input and the main logic… Now it is time to refactor the application to use functions. This should make the code readable and we could re-use parts later. One of those re-usable parts is the number reading. We have […]

Functions

Now we have learned the basics of Python programming: variables, collections and loops. If you have followed the examples and the tutorial you might feel that sometimes we use too much code and it can be leveraged a bit. But maybe you do not know how to do it. This article is an excerpt of […]

Loops

Loops allow to loop through the program code and repeat blocks of code until a given condition is fulfilled or not fulfilled. The code which is repeated is called the loop’s body. This article is an excerpt of my book Python 3 in Anger. For a more detailed version take a look at the book.

Decision making with conditionals

This article is an excerpt of my book Python 3 in Anger. For a more detailed version […]

The Python dictionary

In this article I will tell you more about Python dictionaries. Dictionaries are the key-value stores in Python. They enable a fast access of elements because of the hash-table like implementation and that the keys have to be unique. Keys and values are separated with a colon (:) and the whole dictionary is defined between […]

Sets in Python 3

A set is an unordered collection of unique items. Unordered means that this type of collection does not allow indexing and you cannot access their elements through an index like in the case of a list or a tuple. Unique means that every element is only once in the set even if you put the […]

Tuples in Python

This will be a short article about tuples because sometimes you have to use them — or you just simply encounter them. And for these cases it is good to be versed what they can and what they cannot do. This article is an excerpt of my book Python 3 in Anger. For a more detailed […]
