Iterating over key/value pairs in a dict sorted by keys in python

Iterating over key/value pairs in a dict sorted by keys in python

You can iterate over key-value pairs in a dictionary sorted by keys in Python by using the sorted() function along with a for loop. Here's an example:

my_dict = {'b': 2, 'c': 3, 'a': 1} # Sort the dictionary by keys sorted_dict = dict(sorted(my_dict.items())) # Iterate over key-value pairs in sorted order for key, value in sorted_dict.items(): print(f"Key: {key}, Value: {value}")

In this code:

  1. We have a dictionary my_dict with unsorted key-value pairs.

  2. We use the sorted() function to sort the dictionary by its keys. sorted() returns a list of key-value tuples, which we convert back into a dictionary using dict().

  3. We then iterate over the key-value pairs in the sorted dictionary using a for loop, and print each key and value.

The output will be:

Key: a, Value: 1 Key: b, Value: 2 Key: c, Value: 3

This code ensures that you iterate over the dictionary's items in sorted order based on the keys.
