A programming language is a set of rules, symbols, and syntax used to create instructions that can be executed by a computer. These instructions, also known as code, can be used to instruct the computer to perform a wide variety of tasks, such as performing calculations, displaying information on the screen, storing and manipulating data, and communicating with other devices.
There are many different programming languages, each designed to be used for a specific purpose or to solve a particular type of problem. Some programming languages are general-purpose and can be used to write a wide variety of programs, while others are specialized and are used to write programs for specific applications or environments.
Programming languages are used by software developers, who write the code that creates software programs and applications. They are also used by researchers, data scientists, and other professionals who use computers to solve complex problems and analyse data.
What are libraries?
A library in a programming language is a collection of pre-written code that can be used in a program to perform specific tasks. Libraries are often used to provide a set of common functions that are needed by many different programs, so that developers don't have to write the same code over and over again.
Libraries can contain a wide variety of code, including functions, classes, data structures, and other types of code. They can be written in the same programming language as the program using them, or they can be written in a different language and accessed through an application programming interface (API).
There are many programming languages in use today, and each language has its own set of libraries. Here are some of the most popular programming languages and some of the libraries that are commonly used with them:
Python
