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

Question

I have a list of dictionaries and want each item to be sorted by a specific value.

Take into consideration the list:

[{\'name\':\'Homer\', \'age\':39},         


        

Answer 1

a = [{'name':'Homer', 'age':39}, ...]

# This changes the list a
a.sort(key=lambda k : k['name'])

# This returns a new list (a is not modified)
sorted(a, key=lambda k : k['name'])
