|
|
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.
