How to get data from such a dictionary?

Question

Python

There is a dictionary:
data ={'a': {'b': {'c': 1}}}
You need to get the value of the key 'c' using this construction data[key], while this option does not fit data['a']['b']['c']. How to do it?

Answer 1

Python 3. but this is a crutch of course.

from functools import reduce


class CustomDict(dict):
    def __getitem__(self, key):
        return reduce(lambda acc, x: acc.__getitem__(x), key.split('.'), super())


data = CustomDict({'a': {'b': {'c': 1}}})

print(data['a.b.c'])

Answer 2

The meaning is the same as

data['a']['b']['c']

((data.get('a')).get('b')).get('c')
