Python sort multi dimensional dict

by

First, you should avoid using reserved words (such as input) as variables (now input is redefined and no longer calls the function input()).

Also, a dictionary cannot be sorted. If you don’t need the keys, you can transform the dictionary into a list, and then sort it. The code would be like this:

input_dict = {11: {'perc': 0, 'name': u'B test', 'cid': 11, 'total': 0, 'pending': 0, 'complete': 0}, 10: {'perc': 0, 'name': u'C test', 'cid': 10, 'total': 0, 'pending': 0,'complete': 0}, 3: {'perc': 9, 'name': u'Atest Pre-requisites', 'cid': 3, 'total': 11, 'pending': 10, 'complete': 1}}
input_list = sorted(input_dict.values(), key=lambda x: x['name'])
print(input_list)
# prints [{'perc': 9, 'complete': 1, 'cid': 3, 'total': 11, 'pending': 10, 'name': u'Atest Pre-requisites'}, {'perc': 0, 'complete': 0, 'cid': 11, 'total': 0, 'pending': 0, 'name': u'B test'}, {'perc': 0, 'complete': 0, 'cid': 10, 'total': 0, 'pending': 0, 'name': u'C test'}]

EDIT

If you wish to keep the keys and use iteritems() as you said in the comments, use this code instead:

input_dict = {11: {'perc': 0, 'name': u'B test', 'cid': 11, 'total': 0, 'pending': 0, 'complete': 0}, 10: {'perc': 0, 'name': u'C test', 'cid': 10, 'total': 0, 'pending': 0,'complete': 0}, 3: {'perc': 9, 'name': u'Atest Pre-requisites', 'cid': 3, 'total': 11, 'pending': 10, 'complete': 1}}
input_list = sorted(input_dict.iteritems(), key=lambda x: x[1]['name'])
print(input_list)
# prints [(3, {'perc': 9, 'complete': 1, 'cid': 3, 'total': 11, 'pending': 10, 'name': u'Atest Pre-requisites'}), (11, {'perc': 0, 'complete': 0, 'cid': 11, 'total': 0, 'pending': 0, 'name': u'B test'}), (10, {'perc': 0, 'complete': 0, 'cid': 10, 'total': 0, 'pending': 0, 'name': u'C test'})]
