Assigning Value To Period Seperated List

[bowlofred]

In what form are these values? Is it a string?

If so, you can just use them as a dictionary key, and set the value to what you want.

>>> d = {}
>>> d['1.1.1.1'] = 'A'
>>> d['1.2.1.1'] = 'B'
>>> d['1.1.2.1'] = 'C'
>>> d
{'1.1.1.1': 'A', '1.2.1.1': 'B', '1.1.2.1': 'C'}
