217 Python is a remarkably powerful dynamic programming language that
218 is used in a wide variety of application domains. Some of its key
219 distinguishing features include: clear, readable syntax; strong
220 introspection capabilities; intuitive object orientation; natural
221 expression of procedural code; full modularity, supporting
222 hierarchical packages; exception-based error handling; and very
223 high level dynamic data types.
