[New-bugs-announce] [issue13252] new decumulate() function in itertools module

[Carlo Verre]

New submission from Carlo Verre <carlo.verre at gmail.com>:

After in Python 3.2 the accumulate() function has been added to itertools module, for self-evident reasons of completeness and symmetry we could add in 3.3 the inverse decumulate() function, which, given the iterable argument p, yields p[0], p[1] - p[0], p[2] - p[1]... Its equivalent python form is in the attached file decumulate.py, below.
