How do I sort a dictionary by value? (34 answers)

Closed 8 years ago.

I have a dict where each key references an int value. What's the best way to sort the keys into a list depending on the values?

Answer 1

>>> mydict = {'a':1,'b':3,'c':2}
>>> sorted(mydict, key=lambda key: mydict[key])
['a', 'c', 'b']

Answer 2

I like this one:

sorted(d, key=d.get)

Answer 3

my_list = sorted(dict.items(), key=lambda x: x[1])

Answer 4

[v[0] for v in sorted(foo.items(), key=lambda(k,v): (v,k))]
