[Baypiggies] Fwd: manipulating lists question

[Vikram K]

yes i am sure. another option could have been to obtain a dictionary like
so:

>>> x
[['cat', 'NM123', 12], ['cat', 'NM234', 12], ['dog', 'NM56', 65]]

>>> zee
{'dog': ['NM56', 65], 'cat': ['NM123,NM234', 12]}

---
The problem is to go from x to zee.
