Start programming in Python. Learn Python programming from scratch

Throughout this course, we will master the key aspects of learning to program in Python.

Interestingly, although Python is often considered a recent programming language, that's not the case. Python was conceived in the 1980s (1989, to be exact), and its first public release was in 1991. However, it started gaining popularity with its version 2 and possibly exploded when its version 3 was released at the end of 2008.

Python has become increasingly popular as a programming language. This is likely due to its simple syntax, making it easy to learn (as it is very close to what is known as pseudocode). Suitable for learning, it has been adopted by multiple universities and institutions to teach the first steps in programming to new generations of programmers.

Now, although Python is a simple language to understand and learn, it has very advanced and increasingly popular uses according to its reputation. Its use for data processing and even implementing advanced tools is remarkable.

So, to start this whole process of learning Python from scratch, let's create our first program with Python, and of course, it will be creating a "Hello World" with Python. So, you'll see that Python's reputation is possibly well-deserved.

Your First Program with Python: Hello World

It might be too early if you haven't set up your environment (we'll see that in the next article), but you'll see how simple your first program with Python will be. It consists of a program that would display the message "Hello World" on the screen to the user who executes it, like this:

print('Hello World')

That's it. There might be details to understand (you'll see them throughout this Python course), but you probably have a clear idea of what this simple Python program does.

In general, the print() function receives the message to be displayed. Since it's text, it needs to be enclosed in quotes '', and that's it. Unlike other languages, you don't need to create main functions or end lines with semicolons. It's that simple. That's Python.

I know several things may generate doubt, so let's take it step by step and continue in the next article to master each aspect of Python gradually.
