Building on what Mark said, when you’re dealing with an OrderedDict, the pop method works seamlessly to preserve the order. I’ve used this approach extensively when working with ordered data structures:
from collections import OrderedDict
my_ordered_dict = OrderedDict([('old_key', 'value')])
my_ordered_dict['new_key'] = my_ordered_dict.pop('old_key')
print(my_ordered_dict)
# Output: OrderedDict([('new_key', 'value')])
The key’s position is retained, which is crucial in scenarios where order matters. For an OrderedDict, this method is both practical and elegant for efficiently achieving Python rename dictionary key.
