Hello All,
I am very new to python. Any help will be highly appreciated. Thanks
I have a list of dictionaries:
a = [{'username': u'John Wang', 'user_utilization': 1.0, 'month': 9,
'user_id': 4, 'year': 2008}, {'username': u'John Wang',
'user_utilization': 1.0, 'month': 10, 'user_id': 4, 'year': 2008},
{'username': u' ', 'user_utilization': 1.0, 'month': 9, 'user_id': 1,
'year': 2008}]
I would like to :
search dictionaries within this list
Care to elaborate ???
create a new list with dictionaries which gives 1 dictionary for every
user with month_year as a key and utilization for that month as a
value
assuming the user_id/month/year combination is unique:
from collections import defaultdict
users = defaultdict(dict)
for record in a:
month_year = "%(month)s_%(year)s" % record
users[record['user_id']][month_year] = record['user_utilization']
print users.values()
