Questions tagged [python]
Python is a dynamically typed, high-level interpreted programming language. Its design focuses on clear syntax, an intuitive approach to object-oriented programming, and making the right way to do things obvious. Python supports modules and exceptions, and has an extensive standard module library. Python is general-purpose and thus used widely, from the web to embedded systems.
