How can I sort dict keys using a tuple or a list and than return values? For example, I have a dict:
d = {'a' : 1, 'b' : 3, 'c' : 5, d : '7'}
and a tuple:
t = ('d', 'b', 'c', 'a')
I would like to get a list of values, like:
[7, 3, 5, 1]
Many thanks!
You can use a list comprehension:
>>> [d[k] for k in t]
['7', 3, 5, 1]
or map
:
>>> map(d.get, t)
['7', 3, 5, 1]
You can also create an OrderedDict
using the items in t
:
>>> from collections import OrderedDict
>>> dic = OrderedDict((k, d[k]) for k in t)
>>> dic.values()
['7', 3, 5, 1]
