To add numbers from a file

Right now, I am trying to include only two arguments and I have been using the code below. 

for i in d2:
    for j in D1:
        x[j] = d2[i]-D1[j]
        for k in D1:
            if (x[j] == D1[k]):
                break
print d2[i] = D1[j] + x[j]

ERROR

When I tried to run the code, I got this error:

Traceback (most recent call last):
   line 11, in <module>
    x[j] = d2[i]-D1[j]
IndexError: list index out of range

Checking the sum of all pairs are in another list (off the top of my head):

import itertools as it

D1 = ...
D2 = ...
def my_check(list1, list2):
    for x, y in it.combinations(list1, 2):
        if x+y in list2:
            yield x, y

for x, y in my_check(D1, D2):
    print("{} = {} + {}".format(x+y, x, y))
