python iterating over dictionaries sorted by values

Piece of code below. Can anyone explain why iterating over dictionary, last lines, that has been sorted by values still outputs dictionary not sorted by values? Same applies when I try saving the dictionary.

#!/usr/bin/python

x = {1: 2999, 3: 4, 4: 3, 2: 1, 0: 0 }
srtkeys = sorted(x, key=x.get)
ds={}
print "\ncreating dict sorted by values"
for w in srtkeys:`enter code here`
        print w,x[w]
        ds[w] = x[w]

print "\nprinting dict sorted by values"
print ds

print "\niterating over dict sorted by values"
for k,v in ds.iteritems():
        print str(k)+":"+str(v)

Output:

creating dict sorted by values
0 0
2 1
4 3
3 4
1 2999

printing dict sorted by values
{0: 0, 1: 2999, 2: 1, 3: 4, 4: 3}

iterating over dict sorted by values
0:0
1:2999
2:1
3:4
4:3
