Don't try to 'swap' the dict, just sort a list based on the items in
the dict. Try this:
original= {
'hello':135,
'goodbye':30,
'lucy':4,
'sky':55,
'diamonds':239843,
'yesterday':4 }
items = sorted( (v,k) for (k,v) in original.iteritems() )
items.reverse() # depending on what order you want
print items
The result is:
[(239843, 'diamonds'), (135, 'hello'), (55, 'sky'), (30, 'goodbye'), (4,
'yesterday'),
(4, 'lucy')]
