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>}]

This sounds like a homework assignment. If you're having trouble
with this, sending mail from Python is really going to be a headache
for you.
You want something like
inlist = [{'count': u'2', 'manu': <Manufacturer: Manu1>}, {'count': u'4',
> 'manu': <Manufacturer: Manu2>}, {'count': u'2', 'manu': <Manufacturer:
> Manu3>}, {'count': u'2', 'manu': <Manufacturer: Manu2>}]
outdict = {}
for mandict in inlist :
if not outdict.has_key(mandict[manu]) # if first for this manu
outdict[mandict[manu]] = [] # make empty list
outdict[mandict[manu]].append(mandict) # append entry to list
You now have the desired result in a dictionary, which you can convert to a list
if you like.
If it's a production job, and the number of manufacturers is large,
you're probably better off using a database like MySQL, or some
mail merge program.
