user input values into list of lists

[tauros73]

I have the following code :

import itertools
from functools import reduce
CountOfCombination= 0
for i in itertools.product((1,2),(1,2,0),(1,2)):
       CountOfCombination += 1
       print('For combination {0} is product of values {1} and sum{2}'.format(i, reduce(lambda a, b: a*b,i),reduce(lambda a, b : a+b,i)))

print ('Count of combination is {0}'.format(CountOfCombination))

I would like to populate a variable for the cartesian product via user input, something like this :

import itertools
cont = ""
index = 0
a=[]
while (cont != "N"):
    tips = input("Input combination :  ")
    for i in range(len(tips)):
        a[index][i] = tips[i]
        index += 1
        cont = input("Contiune? [Y/N]")

where a[] would replace

(1,2),(1,2,0),(1,2)
