    ...data structure. Although its dictionaries can be used as lists, this caused unnecessary complexity in practice. Lua code is easy to follow for short scripts, but its syntax and minimal standard library makes it unmanageable for larger programs. In a very important project, the Finnish Civil Aviation Administration (FCAA) wanted to run their user interface layouts not just on the PowerPanel, but also in the context of a web browser. This requirement was important enough that it led to re-imple...

  • Foreword for "Programming Python" (1st ed.)

    ...data types turned out to be less efficient than we hoped. There was too much emphasis on theoretically optimal algorithms, and not enough tuning for common cases. I also felt that some of ABC's features, aimed at novice programmers, were less desirable for the (then!) intended audience of experienced Unix/C programmers. For instance: ABC's ideosyncratic syntax (all uppercase keywords!); some terminology (e.g. "how-to" instead of "procedure"); and the integrated structured editor, which...

    ...data feeds all of which are proprietary in some way and are constantly changing. Python repeatedly has allowed us to access, build and test our in-house communications with hundreds of travel suppliers around the world in a matter of days rather then the months it would have taken using other languages. Since adopting Python 2 years ago, Python has provided us with a measurable productivity gain that allows us to stay competitive in the online travel space," said Michael Engelhart, CTO o...

Client-Side Bliss Another design goal for the system was to simplify client-side programming as much as possible, in order to make it easy to adopt the new technique.

The race has been repaired. A sync() method was also added so that shelve can guarantee data is written to disk. The close() me...

There are many different sound file formats (usually recognized by their extension, e.g. .wav, .aiff, .au), so you may need to create and maintain a growing collection of modules for the conversion between the various file formats. There are also many different operations you might want to perform on sound data (e.g. mixing, adding echo, applying an equalizer function, creating an artificial stereo effect), so in addition you will be writing a never-ending stream of modules to per...
