merge 2 lists with tuple and list and integer

I have 2 lists with tuple and list inside them, how could I merge them together that result would be like this

values 6,0 never changes, only values like 3120 can change alost ther can bet multiple integers in the second list like list1 = [(6, 0, [3120,2121,14141])]

list3 = [(6, 0, [3120, 3116])]

my lists

list1 =  [(6, 0, [3120])]

and 

list2 = [(6, 0, [3116])]

You can do as below assuming length of list1 and list 2 are equal.


list1 =  [(6, 0, [2,4,8]),(3, 5, [3,5,7]),]
list2 =  [(6, 0, [10,12,14]),(3, 5, [9,11,13,15]),]

final_list = []

for i, v in enumerate(list1):
    list3 = [(list1[i])] + [(list2[i])]
    final = list3[0][:2] + tuple([list3[0][2] + list3[1][2]])
    final_list.append(final)

print(final_list)

Out[1]: [(6, 0, [2, 4, 8, 10, 12, 14]), 
         (3, 5, [3, 5, 7, 9, 11, 13, 15])]

You can try it this way, provided the first two items in the tuple won't change as per the question.

list1 =  [(6, 0, [3120])]
list2 = [(6, 0, [3116])]

def add_two_lists(list1, list2):
    # Destructure the first element which is a tuple in both lists
    l1_first, l1_second, rest_first = list1[0]
    l2_first, l2second, rest_second = list2[0]
    res_tuple = (l1_first, l1_second, rest_first + rest_second)
    res_list = [res_tuple]
    return res_list

print(add_two_lists(list1, list2))

You can do this for your example input:

list3 = [list1[0][:2] + tuple([list1[0][2] + list2[0][2]])]
# [(6, 0, [3120, 3116])]

Works for multiple values in the list:

list1 = [(6, 0, [3120,2121,14141])]
list2 = [(6, 0, [3116])]

list3 = [list1[0][:2] + tuple([list1[0][2] + list2[0][2]])]

print(list3)
# [(6, 0, [3120, 2121, 14141, 3116])]

This should do the trick for you:

list1 =  [(6, 0, [3120])]

list2 = [(6, 0, [3116])]

temp_list1 = list(list1[0])

temp_list2 = list(list2[0])

temp_list1[2].append(temp_list2[2][0])

final_tuple= tuple(temp_list1)

list3=[]
list3.append(final_tuple)

print(list3)

prints:

[(6, 0, [3120, 3116])]
