reduce(function, sequence[, initial]) -> value
Apply a function of two arguments cumulatively to the items of a sequence,
from left to right, so as to reduce the sequence to a single value.
For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates
((((1+2)+3)+4)+5). If initial is present, it is placed before the items
of the sequence in the calculation, and serves as a default when the
sequence is empty.

The key is constructed in a way that is flat as possible rather than

If there is only a single argument and its data type is known to cache
its hash value, then that argument is returned without a wrapper. This
saves space and improves lookup speed.

If *maxsize* is set to None, the LRU features are disabled and the cache
can grow without bound.
If *typed* is True, arguments of different types will be cached separately.
For example, f(3.0) and f(3) will be treated as distinct calls with
distinct results.
Arguments to the cached function must be hashable.
View the cache statistics named tuple (hits, misses, maxsize, currsize)
with f.cache_info(). Clear the cache and statistics with f.cache_clear().
Access the underlying function with f.__wrapped__.

a Computes the method resolution order using extended C3 linearization.
If no *abcs* are given, the algorithm works exactly like the built-in C3
linearization used for method resolution.
If given, *abcs* is a list of abstract base classes that should be inserted
into the resulting MRO. Unrelated ABCs are ignored and don't end up in the
result. The algorithm inserts ABCs where their functionality is introduced,
i.e. issubclass(cls, abc) returns True for the class itself but returns
False for all its direct base classes. Implicit ABCs for a given class
(either registered or inferred from the presence of a special method like
__len__) are inserted directly after the last ABC explicitly listed in the
MRO of said class. If two implicit ABCs end up next to each other in the
resulting MRO, their ordering depends on the order of types in *abcs*.
