# 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:

```python
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:

```python
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()` function:

```python
sorted_list = sorted(my_list, key=lambda x: x['age'], reverse=True)
```
