Needing python experts to help with a problem

[gms]

Hello,
I have the following list:

[{'count': u'2', 'manu': <Manufacturer: Manu1>}, {'count': u'4',
'manu': <Manufacturer: Manu2>}, {'count': u'2', 'manu': <Manufacturer:
Manu3>}, {'count': u'2', 'manu': <Manufacturer: Manu2>}]

My current list currently contains four dictionaries.  They are:

{'count': u'2', 'manu': <Manufacturer: Manu1>}
{'count': u'4', 'manu': <Manufacturer: Manu2>}
{'count': u'2', 'manu': <Manufacturer: Manu3>}
{'count': u'2', 'manu': <Manufacturer: Manu2>}

I need to create a list for each specific Manufacturer.  Since I have
two dictionaries that have 'Manu2' as it's manufacturer.  I will need
some code that will create the following from the list above:

[{'count': u'2', 'manu': <Manufacturer: Manu1>}]
[{'count': u'4', 'manu': <Manufacturer: Manu2>},{'count': u'2',
'manu': <Manufacturer: Manu2>}]
[{'count': u'2', 'manu': <Manufacturer: Manu3>}]

The reason for this is because I want to send one email to each
manufacturer.  In this case I would send two emails to Manu2 because I
have two dictionaries that have Manu2 as the manufacturer.  That is
why I need to create a separate list for each manufacturer.

Any help on on how best to do this would be greatly appreciated!

Thanks
