Output

To shorten the code while maintaining functionality, we can utilize the dictionary `get` method which allows a default value if the key is missing. Here's the concise version: 

1
2
def foo(arr, keys):
    return [[x.get(y,-5) for y in keys] for x in arr]
This replaces the explicit key existence check `y in x` with the more compact `x.get(y, -5)` dictionary method, achieving the same result in fewer characters.

Check if all of the following conditions are true:

answer = foo([{1: 2, 3: 4, 5: 6}], [1, 2, 3, 4])
expected = [[2, -5, 4, -5]]
assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
print('All tests passed')
And got the output: All tests passed
