What is Python Programming Language: Basics, Features and Perspectives
Today we'll talk about what Python is, why it is good and why thousands of beginners and experienced IT specialists rush to teach it at breakneck speed.
What is Python?
Python is a general-purpose programming language that is widely used in a variety of fields, from the creation of trivial web pages to rover control systems on other planets.
The scripting language, it is universal and is the most popular programming language in the world (according to the publication Tiobe, which compiles the tops of the most popular languages).
What is written in Python?
What you like. Any software product, regardless of complexity and specifics, can be created in Python and one of hundreds of frameworks developed for it.
To create web applications and sites, third-party libraries are used in the spirit of Pyromid, Flask, Django and dozens of others to help replace PHP and jаvascript.
They even write full-fledged data management systems in Python, which later become analogs of mastodons like WordPress and Drupal. Also, in Python, they create auxiliary tools for working with the web, for example, scrapers that collect information from other people's web pages.
Python has been used to create powerful applications and frameworks such as the GIMP image editor, the Ubuntu operating system app store, 3D graphics editors, bittorrent networks, and more. The list goes on and on.
Also, Python often becomes an integral part of such applications. For example, Sublime Text is written in C++, and extensions and plugins for it are written in Python.
So Python can often be found in completely unexpected places.
IOS and Android apps are built in hundreds of different languages, including Python. More often, of course, this concerns their server component, because more common frameworks or some highly specialized technologies are responsible for the interface. However, Python is often responsible for the backend (that is, the internal logic of the program).
Python is used in game development precisely because of the ability to create robust and well-thought-out scripts with the language. They are responsible for the movement of characters, the performance of any actions, the transition from one event in the game to another, and so on.
Therefore, Python can be found under the hood of many hit games, many of which you probably managed to play (the very popular World of Tanks).
But if desired, the language can be used to create graphical interfaces.
Of course, Windows or Linux are not written in Python (although the language is built into many of these OSs by default), but subsystems for ATMs or mini-computers like the Raspberry Pi are often created using Python. The same applies to machine tools, automated temperature control mechanisms, etc.
Where else is Python used?
Python has many faces, and some of them spud all of science. There are tools like NumPy and Matplotlib that are heavily used in the scientific field. Experts from NASA and other large corporations use Python scripts for serious calculations.
Mathematicians and physicists love Python with all their hearts, and for them it is one of the most used languages. Experts use Python to write fully functional neural networks, program the behavior of robots, create powerful data analysis systems on the Internet that can process colossal amounts of text and numbers.
A lot of "serious" work is done using Python. What can I say if this language helps us not only on Earth, but also occupies our neighbor with might and main.
Why is Python so good?
Python is a scripting language with a fairly simple syntax. It is easier for beginners than other languages, and experts have already managed to adapt it for a huge range of tasks. Everyone was happy, because the structure and logic in Python satisfies the needs of all categories of developers, regardless of their skills and field of activity.
When developing in Python, in most cases, you need to write much less code than when working with its competitors. The syntax itself is visually cleaner and extremely logical.
- The language works on all platforms, so it can be used to develop programs on anything and for anything.
- The language has tremendous support and a truly impressive collection of add-ons from third-party developers.
- It has dynamic typing (you can pass any data type to a function without first specifying it).
- It is interpretable, which allows you to find errors in software earlier (before it is fully assembled into a full-fledged application).
Also Python is famous for its error reporting system. The language makes it very clear where and why the error occurred. Unlike the same C++.
Main disadvantages of Python
- Python is slow. He is capable of a lot, but he does a lot slower than his competitors.
- Python does not use memory very adequately and often "eats" more resources than jаvascript or C would use to solve the same problems.
- Python is strictly tied to system libraries. Hence, difficulties arise when trying to use the language on new software platforms.
What applications are written in Python?
Python is at the heart of dozens of the largest software products on the planet. These include Instagram - the back-end of the application, Google, Spotify, Netflix, Uber, Dropbox, Pinterest, Reddit, etc.
As you can see, your favorite sites and applications use this language, which clearly hints at your endless possibilities when owning Python.
Jobs and salaries
Python is a popular programming language, and finding a job knowing it is not so difficult. There are a lot of vacancies: from the simplest internship positions (making basic scripts) to working in the largest corporations on the planet (creating the most complex infrastructures).
The salary varies depending on the job to be done. Beginners receive from 40 thousand rupees. But there are also quite impressive rates - from 1,000,000 rupees per month. There is a lot of work both in India and abroad.
Where to learn?
Python is taught by many online platforms Hundreds of courses are offered on Coursera and Udemy. If there is no desire to pay, then selfless Indians from YouTube will help you. There are thousands of educational videos on the site, many of which are better than lectures from professors.
In addition, the language has full documentation, which is on the official website and is available to everyone. There is an abundance of information on the language.
Instead of a conclusion
Python is versatile, promising, and relatively easy to learn. An ideal choice for those who want to try IT development, but do not yet know what kind of products they want to create.
