Dynamic Allocation of Nested Dictionaries

[Larz60+]

Hello,

Here's a class for dynamically allocating a dictionary with an example

#
import collections


class DynamicNestedDict:
    def dynamic_nested_dict(self):
        return collections.defaultdict(self.dynamic_nested_dict)


# Example of usage
if __name__ == '__main__':
    keylist = ['bind', 'application level', 'binding']
    loc = [20, 96, 100, 101, 102, 104, 105, 115, 193, 434, 546]

    dd = DynamicNestedDict()
    ddict = dd.dynamic_nested_dict()

    x = 'ddict'
    for n in range(len(keylist)):
        x = '{}[{}]'.format(x, repr(keylist[n]))
    x = x + ' = loc'
    exec(x)

    print("ddict['bind']['application level']['binding']: {}"
          .format(ddict['bind']['application level']['binding']))

Any improvements appreciated
