Python is an interpreted, object-oriented, high-level programming language with strict dynamic typing. It was developed in 1990 by Guido van Rossum and since then has become one of the most popular programming languages. Python is used in many fields such as web development, scientific research, machine learning, game development, robotics, cybersecurity and many more. Python can be used to create a variety of programs, from simple scripts to complex web applications. Python is also used for scientific software development, data analysis, image processing, game development, robotics, cybersecurity, and more. Python is considered one of the easiest languages for beginners to learn programming. Recommended for learning as the first programming language for beginners (for schoolchildren, students). On this site, you will be able to go through the basics of the Python language, as well as Python-based technologies such as NumPy, SciPy, Pandas, Matplotlib, Django.
• Java Tutorial — lessons on Java — a programming language used to create application programs in a wide variety of areas and fields activity Java is one of the most popular programming languages in the world. Java is considered a universal programming language that can be used to program any mechanism, robot or machine. Java is also used to develop mobile applications, web applications, desktop applications, games and much more. The most famous operating systems that were written in the Java programming language: Android OS, BlackBerry Tablet OS and JavaOS.
• Kotlin Tutorial — lessons on Kotlin is a modern, relevant programming language released by JetBrains in 2016. Kotlin is easy to learn, especially if you already know Java (Kotlin is 100% compatible with Java). Kotlin is used to develop Android apps, backend apps, and more. Kotlin runs on various platforms (Windows, Mac, Linux, Raspberry Pi, etc.). On this site, you can learn the basics of the Kotlin programming language.
• Go Tutorial — lessons on Go (or Golang) is a cross-platform open source programming language. Go can be used to create high-performance applications. Go is a fast, statically typed, compiled language that looks like a dynamically typed, interpreted language. Go was developed at Google by Robert Griesemer, Rob Pike, and Ken Thompson in 2007. The syntax of Go is similar to C++. Go is used for: web development (server-side), network application development, cross-platform enterprise application development, cloud native development. On this site you can learn the basics of the Go programming language.
• C Tutorial — C lessons is a general purpose programming language created by Dennis Ritchie at Bell Laboratories in 1972 year It is a very popular language, despite the fact that it is quite old. The C language is closely associated with UNIX because it was developed to create the UNIX operating system. The C language is very powerful; it was used and continues to be used for the development of operating systems, databases, programs, etc.
• C++ Tutorial — lessons on C++ (C plus plus) is a very popular programming language. C++ is used to create computer programs and is one of the most popular languages in game development. C++ is a cross-platform language that can be used to create high-performance applications. C++ was developed by Bjarne Straustrup as an extension of the C language. The C++ language gives programmers a high level of control over system resources and memory. C++ is also called an improved version of the C language — one of the main and first programming languages invented by programmers. Programmers jokingly refer to C++ as C on anabolics because it offers more programming options than C. C++ can be found in modern operating systems, graphical user interfaces, and embedded systems. C++ is an object-oriented programming language that provides a clear structure to programs and enables code reuse, reducing development costs. C++ is portable and can be used to develop programs that can be adapted to many platforms.
• C# Tutorial — C# Tutorials (C-Sharp) is a programming language developed by Microsoft that works on the .NET Framework platform. It was created by Anders Heilsberg and his team at Microsoft in the early 2000s as part of the .NET Framework.
