euporie.core.filters.reduce()

Apply a function of two arguments cumulatively to the items of an iterable, from left to right.

This effectively reduces the iterable to a single value. If initial is present, it is placed before the items of the iterable in the calculation, and serves as a default when the iterable is empty.

For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates ((((1 + 2) + 3) + 4) + 5).
