Create a dictionary by keys and values

Question

I'm trying to create a dictionary dico which contains elements like this:

<key>           <values>
comb_element     pageId1, pageId2, .. pageIdn

comb_element are elements of list of tuple comb :

I try with this code to create dico, but I didn't get the correct format of dico

comb=list(set(product(data['OsId'], data['BrowserId'])))
dico={}
dico[tuple(comb)] = list(data['PageId'])

Here what contains comb :

[(12, 16),
 (33, 11),
 (99, 11),
 (11, 14),
 (33, 14),
 (32, 12),
 (99, 14),
 (11, 11),
 (11, 17),
 (32, 15),
 (99, 17),
 (33, 17),
 (11, 99),
 (33, 99),
 (99, 99),
 (12, 12),
 (12, 15),
 (32, 11),
 (11, 16),
 (33, 16),
 (32, 14),
 (99, 16),
 (32, 17),
 (32, 99),
 (12, 11),
 (12, 14),
 (12, 17),
 (12, 99),
 (11, 12),
 (99, 15),
 (33, 12),
 (99, 12),
 (11, 15),
 (32, 16),
 (33, 15)]

Here the dataframe data: in case of (12, 16) as key I would like to attribute the lis of page : 1005581 and 1016529.

Cluster PageId     OsId BrowserId   
0         1005581   11  16  
0         1016529   11  16  
0         1016529   11  17  
0         1016529   12  14  
0         1016529   12  16  

So for example, any idea to fix it? thanks
