Python Tutorial

Python is a programming language that has conquered the world thanks to its simplicity and power. This language has become a favorite of many programmers and developers due to its ease of learning and the multitude of convenient tools that facilitate work on various tasks.

In this article, we will introduce you to the exciting world of Python and show you how to use this language to solve various tasks. You will learn about the basic commands, and we will also explore interesting examples and projects that will help you understand how to apply Python in practice.

Get ready for an exciting journey into the world of programming with Python, where you define the limits, and the possibilities are endless!

Let's introduce ourselves to our first command and write our first program

The print function is a special command in the Python programming language that allows you to display text and values on the screen for users to see. It's a very useful command for showing the results of your program's execution or for presenting messages.

Here's how it works:

You specify what you want the print function to display by providing arguments inside parentheses. For example:

So, the print function helps you visualize the results of your program and present information to the user. It's one of the fundamental tools for displaying information in Python.

Variables and data types in programming are important because they allow us to store, manipulate, and interact with information. Let's take a look at some of them.

Variables

A variable in Python is a name used to store data. Variables are used so that you can store, retrieve, and manipulate data during the execution of a program.

List

We can also write a set of values in a variable. Such groups of values are called lists.

Python has many more data types. You can learn more about these and other types of data in the following courses:

• Data Types in Python

• Python Data Structures

Let's take a look at the commands we just learned within a real program.

This program creates a password for you using random characters. Here's how it does it:

• We have a list of different characters that can be in the password. This includes uppercase and lowercase letters, numbers, and special characters like @, #, $, and so on.

• The program decides how many characters the password should have. It could be anywhere from 8 to 20 characters long.

• Next, the program picks a random character from the list and adds it to the password. It does this as many times as needed to reach the desired password length.

• When all the characters are added, the program displays the generated password on the screen.

So, you get a password with random characters, making it safe to use, like for logging into your online accounts.

Of course, a program cannot consist of just variables and lists, but knowledge of these topics can serve as an excellent foundation to start writing code and exploring new programming concepts.

Python is undeniably one of the fundamental languages that anyone aspiring to excel in programming should learn. Its simplicity, readability, and wide range of applications make it a cornerstone for both beginners and experienced developers.
