Is there any way to order key values of a dictionary when appending them to a list?

As of now I can append the key values of a dictionary to an empty list, but the goal is to print them in order of the keys in the dictionary.

Here's what I have so far:

DATA = {'Temp1':1, 'Temp2':2, 'RPM1':3, 'RPM2':4, 'Depth1':5, 'Depth2':6, 'A1':7, 'A2':8, 
'KWH1':9, 'KWH2':10, 'V1':11, 'V2':12}

vals = []

for value in DATA.itervalues():
    vals.append(value)

print vals

So I want to print the key value of 'Temp1', 'Temp2', 'RPM1', etc. in the specific order they're listed in the dictionary.

Dictionaries **have no order**. – Martijn Pieters May 14 '14 at 14:22
there is no order in dictionary, it is an unordered data structure. – m.wasowski May 14 '14 at 14:22

You tagged your post with `ordereddictionary`, but are not using one. Perhaps you want to learn what it is: https://docs.python.org/2/library/collections.html#collections.OrderedDict – Martijn Pieters May 14 '14 at 14:23
you can sort the keys by the values which will match the order of your DATA example but that will only work as the values happen to ascend in line with the order you want your keys. – Padraic Cunningham May 14 '14 at 14:28
