    ...API. Operations can be performed on any child node from any parent node, transparently. IceBridge Graphical Console The IceBridge console is a multi-platform application written in Python (using the QT/PyQT toolkit/wrapper for the user interface) that provides all tools needed for development, configuration, management and interactive use of the Application Server system. Like the Application Server's components, the console is a plugins-based system. Plugins are dynamically downloaded from th...

  • Glue It All Together With Python

    ...API, JPython can use arbitrary Java classes without the help of a wrapper generator such as SWIG. (C/C++ code must first be made available to Java through the Java native code interface; once it is callable from Java it is callable from JPython.)

    ...API is standardized and modules exist for MySQL, Postgres, Interbase, Oracle, ODBC, Sybase, and others. Fetch XML from the web? Python's urlparse and urllib standard libraries were made for that. Handle Unicode? Python 2.0 fully supports Unicode out of the box. Implementing the first prototype version took a few weeks of spare time programming and turned out to be very successful. Python provided a much shorter path from concept to implementation than any of the other programming languages we ...

New or upgraded modules and packages Many new doctest extensions from Jim Fulton, which among other enhancements, allows doctests to be run by unittests. csv - support for reading and writing files in so-called comma-separated-value format.

    ...API) which would hide all the complications inherent to networked client/server interaction. Client side agents for Java and Windows' COM interface made this possible by enabling access to the Web services from all major client application environments such as Visual Basic (VB), Visual Basic for Applications (VBA as used in Word, Excel, and Access), Delphi, C++, Java, C# and others. These not only hide the protocol level from the application programmer, but also provide the key to enabling secur...

    ...API. The IFC is built on top of Postgres, with an Oracle version in the works, but it is possible to use any full-function RDBMS, as we took care to avoid non-standard SQL functionality and isolated the DB-specific idioms into a separate portability layer. Production IFCs currently run only under Linux, with others planned. The Business Logic is a layer of rules which handle data validation, access control, and customizable business-specific knowledge held by the customer organization. The Busin...

However, as we discovered the extensive collection of libraries and modules available for it, we decided that Python could be used exclusively. Implementation Our next meetings were with Tom Elliott, the Director of the Ancient World Mapping Center, who conveniently holds an undergraduate degree in Computer Science. He ...

  • Python Patterns - An Optimization Anecdote

Given the effort of writing and testing an extension (compared to whipping up those Python one-liners), as well as the dependency on a non-standard Python extension, I decided not to pursue this option... Conclusion If you feel the need for speed, go for built-in functions - you can't beat a loop written in C. Check the library manual for a built-in function that does what you want. If there isn't one, here are s...
