i have ordereddict , in loop want index, key , value. it's sure can done in multiple ways, i.e. a = collections.ordereddict({…}) i,b,c in zip(range(len(a)), a.iterkeys(), a.itervalues()): … but avoid range(len(a)) , shorten a.iterkeys(), a.itervalues() a.iteritems(). enumerate , iteritems it's possible rephrase as for i,d in enumerate(a.iteritems()): b,c = d but requires unpack inside loop body. there way unpack in statement or maybe more elegant way iterate? you can use tuple unpacking in for statement : for i, (key, value) in enumerate(a.iteritems()): # i, key, value >>> d = {'a': 'b'} >>> i, (key, value) in enumerate(d.iteritems()): ... print i, key, value ... 0 b side note: in python 3.x, use dict.items() returns iterable dictionary view. >>> i, (key, value) in enumerate(d.items()): ... print(i, key, value)
