Iterate through a list of dictionary and append a new value.

[erina]

I'm trying to iterate through the following dictionary and append in the list .

dic={'Dining': [{'Switchboard': [{'Fan': ['01:45.9166666666']},
                             {'Covelight': ['01:116.5']},
                             {'Light': ['01:182.4']}]}],
 'Kids': [{'Switchboard': [{'Light': ['01:206.8']},
                           {'Fan': ['01:2.58333333333']}]}],
 'Kitchen': [{'MultiSensor': [{'Red': ['01:0.95125']}]},
             {'Switchboard': [{'Light2': ['01:125.2']},
                              {'Light': ['01:176.533333333']},
                              {'Fan': ['01:5.0']}]}],
 'Living': [{'Switchboard': [{'Light': ['01:7.13333333333']},
                             {'Covelight': ['01:17.6']},
                             {'Fan': ['01:6.91666666667']}]},
            {'MultiSensor': [{'Red': ['01:0.508333333333']},
                             {'Green': ['01:4.23333333333']}]}]}

for example if I want to append '02:3.9' in {'Green': ['01:4.23333333333']}
