How can I sort a dictionary by key?
The first approach uses the sorted() function to sort the dictionary’s items (key-value pairs) based on their keys. The items() method of the dictionary returns a view object that displays a list of a dictionary’s key-value tuple pairs.
By applying sorted() to this list of tuples, we get a sorted list of key-value pairs, which we then convert back into a dictionary using the dict() constructor.
sorted_dict = dict(sorted(my_dict.items()))
Another way to sort a dictionary by its keys is to use a dictionary comprehension:
sorted_dict = {k: my_dict[k] for k in sorted(my_dict)}
This approach uses a dictionary comprehension to iterate over the sorted keys of the dictionary (sorted(my_dict)). For each key (k), it creates a new key-value pair in the new dictionary, preserving the original values (my_dict[k]) associated with each key.
