Extracting values of elements in a list of dictionaries

Question

I have a python data-structure as follows:

A = [{\'abc\': \'kjkjl\'},{\'abc\': \'hjhjh\'},{\'abc\': \'78787\'}]

How can I remove the \'abc\' fr

Answer 1

B = []
for key, value in A.iteritems():
    B.append(value)

Answer 2

Given your list as

>>> A
[{'abc': 'kjkjl'}, {'abc': 'hjhjh'}, {'abc': '78787'}]

You can do something like

>>> list(itertools.chain(*[x.values() for x in A]))
['kjkjl', 'hjhjh', '78787']
>>> 

Answer 3

You can use list comprehension:

B = sum((i.values() for i in A), [])

Answer 4

>>> B = [a["abc"] for a in A]
>>> B
['kjkjl', 'hjhjh', '78787']

Answer 5

If all the dicts in A only have one element, you can do this ...

>>> A = [{'abc': 'kjkjl'},{'abc': 'hjhjh'},{'abc': '78787'}]
>>> B = [x.values()[0] for x in A]
>>> B
['kjkjl', 'hjhjh', '78787']
