• Python Success Stories

  ...functional requirements for the web-deployed business applications we were developing. It wasn't long before we found ourselves comparing our Python prototypes favorably to the actual systems we were developing.

  ...functionality of the air traffic control system. This choice was found to be problematic for the layout implementors for a variety of reasons: Limited information is provided on errors, making it hard for developers to locate bugs. Variables are global, not local, by default. Python is exactly the other way around, making programs less prone to error. Lua has no list data structure. Although its dictionaries can be used as lists, this caused unnecessary complexity in practice. Lua code is eas...

  ...function A at the top of the file intermingled with four changes to function Z at the bottom of the file. Now the programmer discovers that function A should never have changed; selective undo allows changes to function A to be rolled back without affecting the changes to function Z.

Older versions of BisonGen generate flex files from token definitions given XML; the recent versions generate re-style regular expressions from similar XML specifications. Error handling also follows the YACC tradition: an yyerror function is invoked. Since unwinding out of a bison parser run is not easy, this function normally only sets a global...
