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