Python is a multi-paradigm language. Being an interpreted language, code is executed as soon as it is written and the Python syntax allows for writing code in functional, procedural or object-oriented programmatic ways. Python is frequently recommended as the first language new coders should learn, because of its focus on readability, consistency, and ease of use. This comes with some downsides, as the language is not especially performant in most production tasks.
Ruby is a high-level, interpreted programming language that blends Perl, Smalltalk, Eiffel, Ada, and Lisp. Ruby focuses on simplicity and productivity along with a syntax that reads and writes naturally. Ruby supports procedural, object-oriented and functional programming and is dynamically typed.
Go is an open source programming language supported by Google. Go can be used to write cloud services, CLI tools, used for API development, and much more.
