flatten sequences in a dictionary

Hi

I wondering if someone could give me a pointer. I have a dictionary
with the following structure:

testDict = dict(foo=((1,2, 3),(1,4,3)), bar=((3,2,1),(9 ,8,7,)),
mumble=((1,2,3) ,))

I am trying to create a list of the the 3 element tuples using
itertools (just for a bit of fun). I'm trying this:

list(itertools. chain(testDict. itervalues())

but that's doesn't work. I think I need a way to convert the iterator
returned by itervalues() into a sequence of iterables. Any clues?

Thanks

Andy

Close! Try:
list(itertools. chain(*testDict .itervalues())

Below is an implementation a 'flattening' recursive generator (take a nested iterator and remove all its nesting). Is this possibly general and useful enough to be included in itertools? (I know *I* wanted something like it...) Very basic examples: >>> rl = , '678', 9]] >>> list(flatten(rl)) >>> notstring = lambda obj: not isinstance(obj, type(''))

A few days ago (see the 'itertools.flatten()?' thread from October 28) I became obsessed with refactoring a recursive generator that yielded the leaves of nested iterables. When the dust settled, I had many flatten functions at hand. So I had to time them. Results below. History of the functions (from flattrial.py): # There are three basic features:

This is my first Python program (it's an improvement of a recursive version by Luther Blissett). Given a list like this: , ]]] It produces the "flatted" version: I think this operation is quite important, and it's similar to the built-in Mathematica Flatten function: l = {{"a", 2, {}, {3, 5, {4}}}}

What am I missing? (this is from 2.4b1, so probably it has been fixed?) def flatten(list): l = for elt in list: ^^^^--must be expecting list instance or other sequence t = type(elt) if t is tuple or t is list: ^^^^--looks like it expects to refer to the type, not the arg

Comrades, During our current discussion of the fate of functional constructs in python, someone brought up Guido's bull on the matter: http://www.artima.com/weblogs/viewpost.jsp?thread=98196 He says he's going to dispose of map, filter, reduce and lambda. He's going to give us product, any and all, though, which is nice of him.

Hi, I am wondering how do I 'flatten' a list or a tuple? For example, I'd like to transform or ] to . Another question is how do I pass a tuple or list of all the aurgements of a function to the function. For example, I have all the arguments of a function in a tuple a=(1,2,3). Then I want to pass each item in the tuple to a function f so that I make a function call f(1,2,3). In perl it is a given, but in python, I haven't figured out
