Learn programming step by step. Each lesson contains plenty of practical code that you can run directly in your browser. Computer programming is the composition of sequences of instructions, called programs, that computers can follow to perform tasks.

Understanding the Context

[1][2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. To understand programming, we need to understand the basic underlying concepts. The following pages explain the basic programming concepts, using code examples, images, and animations. A programming language is how we write code, what keywords we use, to tell the computer what to do.

Key Insights

Different programming languages are used for different purposes, like JavaScript is good for web development, Python is good for AI, and C/C++ is good for programming microcontrollers. This comprehensive programming tutorial has covered the fundamentals you need to start coding. Stay updated with emerging technologies and keep practicing to achieve your goals. Coding and programming are sometimes used interchangeably, but the two concepts are slightly different: coding refers to the act of writing code, while programming refers to creating a set of instructions for a computer to follow, or a computer program. The mission of the Python Software Foundation is to promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers.

Final Thoughts

Programming is the mental process of thinking up instructions to give to a machine (like a computer). Coding is the process of transforming those ideas into a written language that a computer can understand. Execution of a program requires an implementation. There are two main approaches for implementing a programming language – compilation, where programs are translated ahead-of-time to machine code, and interpretation, where programs are directly executed.
