[Tutor] Question on List of Dict

[Sunil Tech]

Danny,
i wrote a method called *merge *below

can you be little clear with an example

I wrote something like this

​​
ids = []
for i in tes:
    if i['a'] not in ids:
        ids.append(i['a'])
print ids


def merge(ids, tes):
    for jj in ids:
        txt = ''
        for i in tes:
            if i['a'] == jj:
                txt = txt + ', ' + i['b']
                i['b'] = txt
    return tes
pprint.pprint(merge(ids, tes))

result is like
[1, 2]

[{'a': 1, 'b': ', this', 'c': 221},
 {'a': 2, 'b': ', this', 'c': 215},
 {'a': 1, 'b': ', this, is', 'c': 875},
 {'a': 1, 'b': ', this, is, sentence', 'c': 874},
 {'a': 2, 'b': ', this, another', 'c': 754},
 {'a': 2, 'b': ', this, another, word', 'c': 745}]


from this result need to take off the other dict so that it'll match the
result_tes = [{'a': 1, 'b': 'this, is, sentence', 'c': '221, 875, 874'},
              {'a': 2, 'b': 'this, another, word', 'c': '215, 754, 744'}]
