How to find a value in a list of python dictionaries?

Have a list of python dictionaries in the following format. How would you do a search to find a specific name exists?

label = [{'date': datetime.datetime(2013, 6, 17, 8, 56, 24, 2347),
          'name': 'Test',
          'pos': 6},
             {'date': datetime.datetime(2013, 6, 17, 8, 56, 24, 2347),
              'name': 'Name 2',
          'pos': 1}]

The following did not work:

if 'Test'  in label[name]

'Test' in label.values()
