Goulib.decorators.memoize(obj)

speed up repeated calls to a function by caching its results in a dict index by params :see: https://en.wikipedia.org/wiki/Memoization

Goulib.decorators.debug(func)

Goulib.decorators.nodebug(func)

Goulib.decorators.timeit(method)

Goulib.decorators.get_thread_pool()

Goulib.decorators.timeout(timeout)

Goulib.decorators.itimeout(iterable, timeout)

timeout for loops :param iterable: any iterable :param timeout: float max running time in seconds :yield: items in iterator until timeout occurs :raise: multiprocessing.TimeoutError if timeout occured

@multimethod(int, int) def foo(a, b):

…code for two ints…

@multimethod(float, float): def foo(a, b):

…code for two floats…

@multimethod(str, str): def foo(a, b):

…code for two strings…
