How do I sort a list of dictionaries by a value of the dictionary?

To sort a list of dictionaries by a value of the dictionary, you can use the sorted() function and specify the key parameter to be a lambda function that returns the value you want to sort by.

Here is an example:

Sort a list of dictionaries by a value of a dictionary in Python

data = [{'name': 'Alice', 'age': 25}, {'name': 'Bob', 'age': 30}, {'name': 'Eve', 'age': 20}]

sorted_data = sorted(data, key=lambda x: x['age'])

print(sorted_data)

The output will be:

[{'name': 'Eve', 'age': 20}, {'name': 'Alice', 'age': 25}, {'name': 'Bob', 'age': 30}]

This sorts the list of dictionaries in ascending order based on the value of the 'age' key. You can also use the reverse parameter of the sorted() function to sort the list in descending order.

Using the reverse parameter of the sorted function in Python

data = [{'name': 'Alice', 'age': 25}, {'name': 'Bob', 'age': 30}, {'name': 'Eve', 'age': 20}]

sorted_data = sorted(data, key=lambda x: x['age'], reverse=True)

print(sorted_data)

The output will be:

[{'name': 'Bob', 'age': 30}, {'name': 'Alice', 'age': 25}, {'name': 'Eve', 'age': 20}]
