"python3 (object-oriented interpreted programming language)"
"Python is an interpreted, interactive, object-oriented programming"
"language that combines remarkable power with very clear syntax."
"This is a new version of the language that is incompatible with the"
"2.x line of releases.  The language is mostly the same, but many"
"details, especially how built-in objects like dictionaries and strings"
"work, have changed considerably, and a lot of deprecated features have"
"finally been removed.  Also, the standard library has been reorganized"
"in a few prominent places."
