Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Python.org Python development takes place using a hosted Subversion repository, with other components at SourceForge. Guido van Rossum is the project's lead developer. In recognition of this role, he's sometimes jokingly called the Benevolent Dictator For Life, or BDFL; the acronym is occasionally used in python-dev postings, especially in a context such as "making that change will require a BDFL pronouncement".
