[Python-ideas] Re: Enhancing iterator objects with map, filter, reduce methods

It's not too hard to create your own dataflow class if you want one. It can start with any arbitrary iterable, and then have your map and filter methods just the same. Cool trick: you can even call your class iter! :) class iter: _get_iterator = iter # snapshot the original def __init__(self, basis): self.basis = self._get_iterator(basis) def map(self, func): return type(self)(map(func, self.basis)) # etc def __iter__(self): return self def __next__(self): return next(self.basis)

Cool tip, thanks!
