  • The Python 2.3 Method Resolution Order

    ...Python 2.2: classic classes maintain their old method resolution order, depth first and then left to right. Therefore, there is no breaking of old code for classic classes; and even if in principle there could be breaking of code for Python 2.2 new style classes, in practice the cases in which the C3 resolution order differs from the Python 2.2 method resolution order are so rare that no real breaking of code is expected. Therefore: Don't be scared! Moreover, unless you make strong use of mu...

    ...Python was a faster way to code (and re-code) the programs that controlled the production pipeline. Python Streamlines Production But Python was not designed just as a replacement for shell scripting and, as it turns out, Python enabled much more for ILM than just process control. Unlike Unix shell scripting, Python can be embedded whole as a scripting language within a larger software system. In this case, Python code can invoke specific functions of that system, even if those functions are w...

    ...code in Perl, and it was a spiky mixture of Perl and Tcl that looked even uglier than my own pure-Perl code. It was at this point I remembered the bit I had set more than six months earlier. This could be an opportunity to get some hands-on experience with Python. Of course, this brought me face to face once again with Python's pons asinorum, the significance of whitespace. This time, however, I charged ahead and roughed out some code for a handful of sample GUI elements. Oddly enough, Python's ...

    ...Python that we were rely on heavily for this, and which we were happy to see supported in IronPython, was the execution of cell formulae and user code in a separate instance of the underlying Python engine. This isolates the user's spreadsheet code from the running instance of the Resolver One application, preventing us from polluting each other's namespace, or from having to share global settings such as the Python recursion limit. Supporting Agile Development Python is a modern, expressive l...

    ...Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages 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. Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no co...
