how to iterate from index n to m of an OrderedDict?

I have an OrderedDict and I would like to iterate over a subset of its elements, from index n to m.I can do it the simple way:

from collections import OrderedDict

d = OrderedDict()
for i in range(10):
    d[i] = i

n = 3
m = 6
c = 0
for i in d:
    if n <= c <= m:
        print(d[i])
    c += 1

but I was looking for something more compact, similar to slicing for lists:

n = 3
m = 6
l = [i for i in range(10)]
for i in l[n:m+1]:
    print(i)

Is there such a mechanism for OrderedDict?

Solution

  • It depends on how your OrderedDict is created (n and m need to consider the index of the items in d), but how about this: 

    d.values()[n:m]
