What is this Python project?
From the README of the project:
Python's
itertools
library is a gem - you can compose elegant solutions for a variety of problems with the functions it provides. Inmore-itertools
we collect additional building blocks, recipes, and routines for working with Python iterables.
What's the difference between this Python project and similar ones?
more-itertools
provides most re-usable functions one would want when working with iterables. By relying on this lightweight package, similarly to what itertools
provide, one can write more readable and maintainable code, while avoiding having to re-invent the wheel (and introducing bugs by doing so).
As simple examples, instead of using raw iterators, one should use itertools
when appropriate:
>>> from itertools import repeat
>>> (10 for _ in range(3)) # Instead of this ...
>>> repeat(10, 3) # ... use that!
and more-itertools
is based on the same idea and provides many more building blocks:
>>> from more_itertools import ilen
>>> sum(1 for _ in iter) # Instead of this ...
>>> ilen(iter) # ... use that!
Of course, the project also provides more advanced expressions, hard to express as one-liners. Some of my favourites (notice their high-quality documentation):
all_equal(iterable)
last(iterable[, default])
nth(iterable, n, default=None)
consume(iterator, n=None)
distribute(n, iterable)
roundrobin(*iterables)
windowed(seq, n, fillvalue=None, step=1)
substrings(iterable)
powerset(iterable)
random_permutation(iterable, r=None)
with_iter(context_manager)
In many cases where I wondered "Why didn't they implement this in itertools
?!", most-itertools
had a single-call solution: there's a reason why the project already has 1.2k
Please give most-itertools
a try and give this PR a
