I have several dictionaries with different and common keys, plus different and common keys in the nested dictionary. Below is a simplified example, the actual dictionaries have
from collections import defaultdict
mydicts = [
{1:{"Title":"Chrome","Author":"Google","URL":"http://"}},
{1:{"Title":"Chrome","Author":"Google","Version":"7.0.577.0"}},
{2:{"Title":"Python","Version":"2.5"}},
]
result = defaultdict(dict)
for d in mydicts:
for k, v in d.iteritems():
result[k].update(v)
print result
defaultdict(,
{1: {'Version': '7.0.577.0', 'Title': 'Chrome',
'URL': 'http://', 'Author': 'Google'},
2: {'Version': '2.5', 'Title': 'Python'}})
