If you combine your dict1 and dict2 to become result_dict, what
should the result of result_dict[3] be? 3 or 5?
It sounds like the .update() method on a dict.
You can do something like
dict2.update(dict1)
or
disc1.update(dict2)
depending on your answer to the above question about what
result_dict[3] should be.
If you need to preserve dict1 and dict2, rather than update one
of them, you can make a copy first:
result_dict = dict(dict1)
result_dict.update(dict2)
this will produce result_dict[3] = 3 whereas if you want it to
return 5, swap the order of dict1 and dict.
