How to sort Python dictionary

Dictionary is one of the commonly used data structures in Python. It can store key-value pairs and has fast search capabilities. However, the internal elements of a dictionary are not in a fixed order, which can be inconvenient in some cases. If we need to sort a dictionary by its keys or values, Python provides several ways to achieve this goal.

Method 1: Use the sorted() function and lambda expression
The simplest method is to use the built-in sorted() function combined with a lambda expression to sort the dictionary. We can use the key parameter of the sorted() function to specify the basis for sorting, and lambda expressions can be used to extract the keys or values ​​of the dictionary.

Here is a sample code that demonstrates how to sort a dictionary by its keys:

my_dict = {
   
    
    'b': 2, 'a': 1, 'd': 4,
