Sorting Lists of Dictionaries
Frequently you want to sort a list of dictionaries, based on some particular key.
For example:
Toggle line numbers
1 a = { "key1":5, "key2":8, "key3":2 }
2 b = { "key1":7, "key2":4, "key3":9 }
3 c = { "key1":6, "key2":1, "key3":1 }
4 l = [ a,b,c ] # how do you sort this list?
There are many ways to do this; Here's one way I've been doing it:
Toggle line numbers
1 sort_key = "key2"
2 l = [(d[sort_key],d) for d in l]
3 l.sort()
4 l = [d for (k,d) in l]
