  • Python Patterns - An Optimization Anecdote

    ...3(), but only by 25%; it was about 40% faster than f1() still. This is because local variable lookups are much faster than global or built-in variable lookups: the Python "compiler" optimizes most function bodies so that for local variables, no dictionary lookup is necessary, but a simple array indexing operation is sufficient. The relative speed of f4() compared to f1() and f3() suggests that both reasons why f3() is faster contribute, but that the first reason (fewer lookups) i...

E.g. for the expression "a+b" it will have to generate a call to PyNumber_Add(a, b) because it can't know the types of a and b without a *lot* (and a mean a LOT) of type inferencing effort.] Later, Mike writes: Okay, trying to debug this weird stack corrupt...

    ...Python as a working title for the project, being in a slightly irreverent mood (and a big fan of Monty Python's Flying Circus). Today, I can safely say that Python has changed my life.

There are Python T-shirts, workshops, mailing lists, a newsgroup, and now a book. Frankly, my only unfulfilled wish is to have my pictu...
