Because inside the for loop, your value 'key' is an item from the sorted
list of the values part of months. When you use months[key], you're
trying to look up in months based on the value part, not the key part.
Calling it key is confusing you.
Try this:
things = { "a":1, "b":3, "c":2 }
for thing in sorted( things.values() ):
print thing
>> Prints 1, 2, 3
for thing in sorted( things.keys() ):
print thing
>> Prints a, b, c
Now although things["b"] is a valid reference because "b" is a key in a
key - value pair, things[3] is not a valid reference, because 3 is not a
key in a key - value pair.
