Python Overview

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it attractive for Rapid Application Development and for use as a scripting or glue language to connect existing components together. Python's syntax emphasizes readability and reduces the cost of program maintenance, supporting modules and packages, to encourage program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Python does not demand a compilation step and edit-test-debug cycle is fast, contributing to efficiency. When the interpreter discovers an error, it raises an exception. When the program misses the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python's introspective power.

I have been working with Internet technology and its challenges since 1989 and our most difficult task is to quickly convert legacy applications and data into a web based application. The best example of this legacy application was the Navy's Engineering Change Proposal Application. An automated tool was supposed to streamline a very common business task. Many contractors and application developers have attempted to automate this process and have failed. We turned to the development product ZOPE and have completely rewritten the meaning of legacy conversions. The ECP application was developed under ZOPE and accepted after an extensive competitive development process.
