In this case, I'll use ‘itertools.groupby’ to make a new sequence of
keys and values, and then extract the keys and values actually wanted.
Ah, yes, Zawinski revisited ... itertools.groupby is the new regex :-)
Certainly it might be clearer
So grateful! Thanks to all. The breadth of Python continues to amaze
me, as does your generosity.
(Relative clarity like relative beauty is in the eye of the
beholder,
and few parents have ugly children... fantastic!)

Hi all,
I am probably not thinking straight anymore about this problem. I
have a dictionary with tuple keys in the format (a, b, A, B) and float
values. I want to collect all the keys with identical (a, b...),
disregarding whatever (... A, B) might be. Specifically, I want to
sum the float

Hi everbody
i am trying to print the dictionary values and tuple in a same line as below
print \t.join(dict[a].values())+'\t'+\t.join(b)
Error I get is the TypeError,

It looks like you want tuple(d.iteritems())
d = {1: 'one', 2: 'two', 3: 'three'}
tuple(d.iteritems())
((1, 'one'), (2, 'two'), (3, 'three'))
You could also use tuple(d.items()). The result is essentially the
same. Only if the dictionary is extremely large does the difference
matter. (or if
