how to define dynamic nested loop python function

Question

a = [1]
b = [2,3]
c = [4,5,6]

d = [a,b,c]


for x0 in d[0]:
    for x1 in d[1]:
        for x2 in d[2]:
            print(x0,x1,x2)

Result:

<

Answer 1

You can use itertools to calculate the products for you and can use the * operator to convert your list into arguments for the itertools.product() function.

import itertools

a = [1]
b = [2,3]
c = [4,5,6]

args = [a,b,c]

for combination in itertools.product(*args):
    print combination

Output is

(1, 2, 4)
(1, 2, 5)
(1, 2, 6)
(1, 3, 4)
(1, 3, 5)
(1, 3, 6)
