clever programming solution wanted

[Scott Rifkin]

If anyone has a good, quick solution to the following in python2.3 
I'd appreciate it:

I have a dictionary with keys K1, K2, ..., K10000
Each entry looks like:

dict[K1]=[T1,T4,T500] 

where the T's are indexed from, say, 1 to 20000 and each K has some number 
of Ts (not always 3).

I want to create groups of Ks which share Ts such the groups are maximal, 
for instance:

dict[K1]=[T1,T4,T500]
dict[K2]=[T1]
dict[K3]=[T500,T7000]

these would be grouped [K1,K2,K3].

At the end, most of the Ks will be by themselves, but some will be grouped 
with some number of other Ks.


Thanks for any help,

Scott Rifkin
