Sort List of Dictionary by Key in Python

Here is example code to perform sorting list of dictionary by dictionary key.
For example I need to sort my list by level.

from operator import itemgetter

tmp = [
    {'name': 'foo', 'age': 35, 'level': 1},
    {'name': 'bar', 'age': 11, 'level': 5},
    {'name': 'john', 'age': 28, 'level': 3},
    {'name': 'doe', 'age': 74, 'level': 9},
    {'name': 'alex', 'age': 12, 'level': 7},
]

print sorted(tmp, key=itemgetter('level'))                # Sort ascending
print sorted(tmp, key=itemgetter('level'), reverse=True)  # Sort descending
