Novice Question: two lists -> dictionary

[frederic pinel]

Here is a quick and dirty answer! Sorry...

ListA = ['10', '10', '20', '20', '20', '24']
ListB = ['23', '44', '11', '19', '57', '3']

ListT = []	# temporary list
Dict = {}

for i in range(len(ListA)):
	ListT = key_values(i, ListA, ListB)
	if (Dict.has_key(ListT[0]) == 0):
		Dict[ListT[0]] = ListT[1:]
		
print Dict	# print results, for test purposes. 


def key_values(i, l_key, l_val):
	" returns a list with the first item being the l_key[i] (ListA), 
	" and the values after for that key (ListB)
	resultat = []
	for j in range(len(l_key)):
		if (l_key[j] == l_key[i]):
			result[0] = l_key[i]
			result.append(l_val[j])
		
	return result

regards,
frederic
