>>> from collections import ChainMap
>>> L = [{'key1': 111, 'key2': 222}, {'key3': 333, 'key4': 444}]
>>> cm = ChainMap(*L)
>>> cm['key1']
111

Of course, you can merge with each other with updates from dict.

Alternatively, the newly introduced grammar from 3.5 can be combined as follows.

>>> L = [{'key1': 111, 'key2': 222}, {'key3': 333, 'key4': 444}]
>>> {**L[0], **L[1]}
{'key1': 111, 'key2': 222, 'key3': 333, 'key4': 444}
