How do I sort a list of dictionaries by a value of the dictionary in Python?
In Python, you can use the
sorted() function to sort a list of dictionaries by a specific value of the dictionary. The
sorted() function takes two arguments: the list to be sorted, and a key function that maps each element of the list to a value that is used for sorting.
For example, if you have a list of dictionaries called
my_list, and you want to sort it by the value of the 'age' key of each dictionary, you can use the following code:
sorted_list = sorted(my_list, key=lambda x: x['age'])
You can also use the
itemgetter() function from the
operator module as the key function, which is more efficient than using a lambda function:
from operator import itemgetter sorted_list = sorted(my_list, key=itemgetter('age'))
If you want to sort the list in descending order, you can pass the
reverse=True argument to the
sorted_list = sorted(my_list, key=lambda x: x['age'], reverse=True)
