Itemizer

class decida.Itemizer.Itemizer(*iterables, **kwargs)

synopsis:

Cross-product iterator with tag.

Each Itemizer iteration produces a list of elements, one from each contributing list of iterators.

At each iteration, the tag() method produces a string for naming or reporting.

constructor arguments:

*iterators (iterables)

variable arguments are each an iterator

tag (str, default=None)

format string for the tag. If None, then tag is “%s. ... %s” (number of iterators)

results:

• the Itemizer instance iterates over the cross-product of all of the specified iterators.
• each iteration produces a list of elements, one from each iterator.
• the tag() method produces a string for naming or reporting.

example (from test_Itemizer):

>>> from decida.Itemizer import Itemizer
>>> procs = ["TT", "SS", "FF"]
>>> vdds  = [0.9, 1.0, 1.1]
>>> temps = [0, 25, 100]
>>> ix = Itemizer(procs, vdds, temps, tag="%s.V_%s.T_%s")
>>> for proc, vdd, temp in ix :
>>>    tag = ix.tag()
>>>    print tag, proc, vdd, temp
