Brilliant suggestion. Worked like a charm. Here is the final product:
def dekeyed(serialized, keyfunc):
for name, series in serialized:
grouped = groupby(series, keyfunc)
regrouped = ((k, (v[1] for v in g)) for (k,g) in grouped)
yield (name, regrouped)
def serialize(table, keyer=_keyer,
selector=_selector,
keyfunc=_keyfunc,
series_keyfunc=_series_keyfunc):
keyed = izip(imap(keyer, table), table)
filtered = ifilter(selector, keyed)
serialized = groupby(filtered, series_keyfunc)
return dekeyed(serialized, keyfunc)
Thank you!
