l=[['a','b'],['c','d']]
ret = []
for i in l:
    item = {}
    for j in i:
        item[j*2] = j
    ret.append(item)
        
print ret
import json
print json.dumps(ret)

[{'aa': 'a', 'bb': 'b'}, {'cc': 'c', 'dd': 'd'}]
[{"aa": " a", "bb": "b"}, {"cc": "c", "dd": "d"}]

import json

def main(list_):
    return json.dumps([{'{key}{key}'.format(key=k): k for k in lst} for lst in (i for i in list_)])


if __name__ == '__main__':
    list_=['a','b'],['c','d']
    print main(list_)     # '[{"aa": "a", "bb": "b"}, {"cc": "c", "dd": "d"}]'
