  • Python Patterns - An Optimization Anecdote

    ...lambda string, item: string + chr(item), list, "") This version performs exactly the same set of string operations as the first one, but gets rid of the for loop overhead in favor of the faster, implied loop of the reduce() function. Sure, I replied, but it does so at the cost of a function call (the lambda function) per list item. I betcha it's slower, since function call overhead in Python is bigger than for loop overhead. (OK, so I had already done the comparisons. f2() t...

  • SIG for development of Python/C++ integration

    ...lambda expressions for describing default arguments. Keyword Argument Support Python supports the specification of particular function arguments by name, rather than by position. Goal: Implementation of a feature which allows keyword arguments to be used from Python for wrapped C++ functions. Generic C++ to Python Object Interface It is often necessary for C++ functions to manipulate objects passed to them directly from Python, without converting them to some ...

  • Notes

    ...lambda statements could reference variables in the namespaces where the lambda is defined. In some unusual cases, this change will break code. In all previous version of Python, names were resolved in exactly three namespaces -- the local namespace, the global namespace, and the builtin namespace. According to this old definition, if a function A is defined within a function B, the names bound in B are not visible in A. The new rules make names bound in B visible in A, unless A contains a nam...

    ...lambda expression. SF bug 705231: builtin pow() no longer lets the platform C pow() raise -1.0 to integer powers, because (at least) glibc gets it wrong in some cases. The result should be -1.0 if the power is odd and 1.0 if the power is even, and any float with a sufficiently large exponent is (mathematically) an exact even integer. SF bug 759227: A new-style class that implements __nonzero__() must return a bool or int (but not an int subclass) from that method. This matches the restriction...
