  • Notes

    ...Function objects now have a __module__ attribute that is bound to the name of the module in which the function was defined. This applies for C functions and methods as well as functions and methods defined in Python. This attribute is used by pickle.whichmodule(), which changes the behavior of whichmodule slightly. In Python 2.2 whichmodule() returns "__main__" for functions that are not defined at the top-level of a module (examples: methods, nested functions). Now whichmodule() wi...

  • Comparing Python to Other Languages

    ...functions and variables without engaging in class definitions. However, for JavaScript, that's all there is. Python, on the other hand, supports writing much larger programs and better code reuse through a true object-oriented programming style, where classes and inheritance play an important role. Perl Python and Perl come from a similar background (Unix scripting, which both have long outgrown), and sport many similar features, but have a different philosophy. Perl emphasizes supp...

    ...functions into the interpreter, to thinking in terms of Python's program flow. Years later, my Python and software management skills have been invaluable. I run a small business, where I've been able to hire, train, and mentor contract workers who then go on to get full-time programming jobs. We've helped overhaul the Python Package Index, mentored and recruited contributors to Zulip, helped journalists open-source their code, and more. Right now I'm leading pip's work replacing its dependency r...

    ...functionality to cause people to begin to switch (outside of astronomy, those will be driven by our libraries that are using numarray) Slower performance for small arrays. Since more of it is written in Python, it is an order of magnitude slower for smaller arrays (but just as fast or faster for large arrays (> 1MB)). Optimization is in our plans, but won't be done until we fill out the libraries and finish the safety issue (which is near completion). Becau...

  • Python Success Stories

    ...definitions or the initializer structure changed. What I really wanted was code that would analyze the shape and members of the initializer, query the class definitions themselves about their members, and then adjust itself to impedance-match the two sets. This kind of thing is called metaclass hacking and is generally considered fearsomely esoteric -- deep black magic. Most object-oriented languages don't support it at all; in those that do (Perl being one), it tends to be a complicated and fra...
