Merging values from separate dictionaries

Lets say I have 2 dictionaries:

dict_a = {'01A': 'X', '02B': 'V', '03C': 'AE'}
dict_b = {'01A': 'V', '02B': 'D', '03C': 'X'}

They essentially have the same keys. What I want is this:

dict_c = {'01A': ['X', 'V'], '02B': ['V', 'D'], '03C': ['AE', 'X']}

What is the proper way to do this?

There are many ways to achieve that, the one could be using defaultdict from collections something like this.

from collections import defaultdict
dict_a = {'01A': 'X', '02B': 'V', '03C': 'AE'}
dict_b = {'01A': 'V', '02B': 'D', '03C': 'X'}
d = defaultdict(list)
for d1, d2 in dict_a.items() + dict_b.items():
    d[d1].append(d2)
print(dict(d))
