By 2022, programming has become so deeply embedded in everyday life that people have stopped noticing how life has changed. Hundreds of thousands of familiar things wouldn’t exist without programming or would be much less convenient to use. Familiar household appliances like a microwave oven or a washing machine work thanks to coding programs.
Computers have allowed us to make some pretty amazing things: global telecommunications, international commerce, global transportation, breakthroughs in medicine, distributed education, online shopping online dating. Computers allow us to explore our world and other worlds in general. And of course, some seemingly mundane things like permitting us to spawn our pets from work or communicating with our friends in a nearly indecipherable stream of emoji but don’t call computers magical.
Topic covered in this article is to introduce CS and programming using python.
- A Notion of computation
- The Python programming language

- Testing and debugging
- An informal introduction to algorithmic complexity
- Data structures
Introduction to CS and programming using python
Start thinking about how to get a computer to do things for us so. We can start by saying well, what are we on the computer to do? We wanted to compute something that sounds like a deep philosophical question. In fact it is that leads to an even deeper philosophical question.
If we want a computer to compute something, we can ask?
Well what’s the knowledge it’s going to use and that leads to an interesting distinction cause we can divide knowledge into two types.
- We’re gonna call it declarative knowledge.
- We’re gonna call imperative knowledge.
If you work with text on a computer, you need to know about coding, even if you send emails and even if you only receive them. It is not necessary to understand every detail, but you should at least know what coding is.
Coding or Programming Features You Should Know
It is no coincidence that in conversations about the labor market, development prospects, and the most important areas in the modern world, the issue of IT, programming, and digital technologies is so often raised. Applications, artificial intelligence, programming languages — these words and phrases evoke many emotions. At the same time, they set the direction for a professional career.
- Since computers don’t understand human language, they use a system of instructions called machine code. It means that every program that the computer understands consists of various combinations of the numbers “1” and “0”.
- Special languages such as C/C++, C#, Java, PHP, and others are used to create the source code. Programs written with these languages are converted through a compiler or interpreted through an interpreter program to translate the source code. It is the essence of the coding process, which involves creating program code to implement the desired algorithm using a specific programming language.
- Coders are the people responsible for writing the underlying code for applications. They can’t participate in other stages of software development, such as design or testing. They are usually considered less trained and less experienced than programmers because they don’t have deep knowledge of algorithms and can only use one language. Coding is the part of programming that is concerned with writing code.
- Encoding doesn’t require a lot of software tools, as it is just the process of translating the code into a machine-readable form. A simple text editor is enough. But as a coder, you must know the syntax of your programming language.
- Coders should have a basic knowledge of programming languages, syntax, and terminology.
- When coding, the expected result is a simple solution or a small part of the project. The code acts as a set of instructions given to the computer.
- Experienced coders (like programming assignment experts on the Assignment Core) understand at least two or three programming languages and write clean, bug-free, well-thought-out code. They can use their algorithmic knowledge to create complex levels of software coding.
- Writing code is only the initial stage of software development. At the same time, the programming process includes creating a project and planning actions to solve potential problems that may arise at different stages of work.
Practical programming introduction to computer science with Python
Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.
What can Python do more powerfully?
- Python’s concise, easy-to-learn syntax prioritises readability, which lowers software maintenance costs.
- Python can connect to database systems. It can also read and modify files.
- Python can be used alongside software to create workflows.
- The debugger is written in Python itself, testifying to Python’s introspective power.
- Python can be used to handle big data and perform complex mathematics.
- Python can be used on a server to create web applications.
- Python can be used for rapid prototyping, or for production-ready software development.
What Are the Benefits of Coding
Interest in programming is growing day by day. Both adults and children participate in it. What motivates a lot of people to become coders? Many like coding for the urgent need to develop analytical thinking that allows you to solve problems effectively. Also, with the help of coding, you can create or master systems that automate and optimize workflows. Such skills are especially valued in today’s business environment where high technology is in charge.
That is why schools began to pay special attention to programming and coding. For primary school students, this task is simplified by special applications. Many sites offer educational courses for free or at an affordable price. The benefits of such resources are obvious both for novice coders and for experienced programmers who want to replenish their professional skills.
As a coder, you will be able to:
- Successfully work with computers;
- Apply the computing power in all your projects;
- Automate tasks;
- Create “smart” machines;
- Claim high earnings and career growth;
- Develop interpersonal skills;
- Understand such marketing concepts as front-end and back-end;
- Get more time for your hobbies;
- Remotely adjust the operating parameters of the system using coding.
Another advantage of coding skills is the ability to work on interesting projects. Some prefer to work full-time in the office, while others get online orders and complete them remotely. Either way, you can make a career as a coder.
IT is a flexible sector. It applies both to employment (employment contract, self-employment, or freelance activities) and the organization of work itself. Working remotely from a home office is a common practice. You can also perform tasks straight from an exotic beach where you sit with your laptop.
Coding is a very rewarding profession. Today, many people can’t imagine working the classic 8-hour model, 5 days a week. Whether due to hobbies, family life, location, or other factors, we increasingly value flexibility. The better and wider the knowledge of programming, the easier it is to negotiate attractive financial conditions and the desired schedule or work model.

This is the first of two courses in a two-part series: Introduction to Computer Science and Python Programming, and Introduction to Computational Thinking and Data Science. They’re designed to help people who have never studied computer science or programming learn to think computationally and build programmes to solve real-world issues. Some students will utilise the two courses as a springboard to more advanced computer science courses, but for many, they will be their first and final computer science courses. This run includes Python 3.10 course videos, lecture exercises, and problem sets. You will be able to simply switch to Python 3.10 in future courses, or enrol now to refresh your understanding, even if you previously took the course with Python 3.10.
We chose to focus on breadth rather than depth because these courses may be the only formal computer science courses many of the students attend. The purpose is to provide students a brief overview of a variety of topics so that they can have a sense of what is feasible when they need to consider how to utilise computing to achieve a goal later in their careers. They are not, however, “computation appreciation” classes. They are difficult and demanding courses in which students devote a significant amount of time and effort to learning how to manipulate computers to their will.
