dictionary - Unpacking a list of dictionaries based on key matches in Python -


i looking way unpack list of dictionaries key id. have seen lot of examples based on key value, nothing on key match. have dictionary in following format returned function...

data = [{'lev1': u'82', 'marker': u'16', 'type': u'139', 'location': u'a'},         {'lev2': u'652', 'marker': u'1', 'type': u'140', 'location': u'c'},         {'lev3': u'452', 'marker': u'188', 'type': u'141', 'location': u'b'}] 

my current attempt shown below, getting >> typeerror: list indices must integers, not str

for item in data:     parts[data['type']].update(data) 

the parts reference above dictionary of parts numbers. looking drop each of following list entries (for example, 'lev1': u'82', 'marker': u'16', 'type': u'139', 'location': u'a') main 'parts' dictionary based on type (there should type match in parts dictionary).

my method works single returned dictionary entry...

parts[data['type']].update(data) 

...but not list of dictionaries.

i looking end format along lines of...

parts{     125:     ...     ...     ...     139:{         'lev1': u'82',          'marker': u'16',          'type': u'139',          'location': u'a'         plus other gathered data         }      140:{         'lev2': u'652',          'marker': u'1',          'type': u'140',          'location': u'c'         plus other gathered data         }      141:{         'lev3': u'452',          'marker': u'188',          'type': u'141',          'location': u'b'         plus other gathered data         }     142:etc     ... } 

you can update item instead of data

for item in data:     parts[item['type']].update(item) 

result

>>> parts {'141': {'lev3': '452', 'type': '141', 'marker': '188', 'location': 'b'},  '140': {'lev2': '652', 'type': '140', 'marker': '1', 'location': 'c'},  '139': {'lev1': '82', 'marker': '16', 'location': 'a', 'type': '139'}}
