How To Sort All The Keys, Sub-keys, Sub-sub-keys, Etc Of A Dictionary At Once?

Is there a way to sort all the keys, sub-keys, sub-sub-keys, etc. of a python dictionary at once? Let's suppose I have the dictionary dict_1 = { 'key9':'value9',

Solution 1:

First, it is important to know that dictionaries are not ordered. So, if you want to order a dict, you need to go with collections.OrderedDict (which exists since Python 2.7).

And then, this is a use case for a recursive function:

from collections import OrderedDict


def order_dict(d):
    ordered_dict = OrderedDict()
    for key in sorted(d.keys()):
        val = d[key]
        if isinstance(val, dict):
            val = order_dict(val)
        ordered_dict[key] = val
    return ordered_dict
