- dictionary2 = {“a”: 3, “b”: 2}
- common_pairs = dict()
- for key in dictionary1:
- common_pairs[key] = dictionary1[key]
- print(common_pairs)
How do you find the index of a dictionary in a list?

What is the outcome of a unit test?
The outcome of a unit test is binary: either “pass” if the program’s behavior is consistent with the recorded expectations, or “fail” otherwise. Developers will typically write a large number of unit tests (corresponding to a large number of program behaviors of interest), called a “test suite”.
