Hello World in Python 3

The classic "Hello, World" program is usually showed in courses and books as the first program that every programmer or student should write when approaching a new language. It is a very simple program that only outputs the sentence "Hello, World".

How to write the "Hello, World" program in Python 3:

Hello World on Python 3.6

In Python, all we need to perform this task is to write the following line in any Python IDE, text editor, or interpreter:

print("Hello World")

The result will be the following:

Hello World

Understanding the Program

This time, we are running a Python 3 shell; an interpreter where can introduce multiple functions and variables, that will run at the moment we press "Enter" on our keyboard, one line at a time (Excepting loops and functions definitions).
We are calling the prebuilt print() function, which allows us to show messages on the screen. As it is a function, we have to put a parenthesis, and we are passing the arguments that the print() function needs to work.
The argument that the print() function gets is a string of characters, in this case, the sentence "Hello World". As it is a sentence and not the name of a variable or a function, we need to put it between quotation marks.

What is Spyder? Spyder is a robust integrated development environment (IDE) for Python with a lot of useful features for scientists, engineers, and data analysts. Spyder is entirely written in Python and comparable with Matlab. Although Spyder is usually included in the Anaconda Distribution , it can run on its own, something that will be enough for most programmers who are looking for one of the best Python IDEs that we can install in our system. Install Spyder on Windows without Anaconda To install Spyder IDE on Windows, we are going to need PIP; if you're not familiarized with PIP, you can look at my post How to install python packages with PIP . Open a command prompt and type the following command to install Spyder : pip install spyder Spyder has multiple dependencies that you can check on the official Spyder documentation . However, PIP will automatically install any not satisfied dependencies making the process very straight-forward. Once you install Spyd

How to install PyQt5 and Qt Designer on Ubuntu

PyQt is the binding of Qt for Python. It allows us to use the graphic framework Qt to create Graphic User Interfaces for our Python programs. Qt is not only a very complete library for GUI development, one of its advantages over other GUI libraries for Python like Tkinter, is its graphic designer: Qt Designer , that we can use to draw graphic interfaces for our programs by dragging and dropping widgets in a window with no need to code, simplifying the process of designing the GUI. Installing Qt and Qt Designer To get Qt Creator and Qt Designer in your system you need to type the following commands in the terminal: sudo apt install build-essential sudo apt install qtcreator sudo apt install qt5-default The build-essential includes all the tools needed to create packages for Debian and Ubuntu, while qtcreator will install Qt Creator, the IDE used to build Qt Apps. qt5-default will allow us to use Qt5 as the default version of Qt in Qt Creator.
