How to extract dictionary single key-value pair in variables
Add another level, with a tuple (just the comma):
(k, v), = d.items()or with a list:
[(k, v)] = d.items()or pick out the first element:
k, v = d.items()[0]The first two have the added advantage that they throw an exception if your dictionary has more than one key, and both work on Python 3 while the latter would have to be spelled as k, v = next(iter(d.items())) to work.
Demo:
>>> d = {'foo': 'bar'}>>> (k, v), = d.items()>>> k, v('foo', 'bar')>>> [(k, v)] = d.items()>>> k, v('foo', 'bar')>>> k, v = d.items()[0]>>> k, v('foo', 'bar')>>> k, v = next(iter(d.items())) # Python 2 & 3 compatible>>> k, v('foo', 'bar')
items() returns a list of tuples so:
(k,v) = d.items()[0]
>>> d = {"a":1}>>> [(k, v)] = d.items()>>> k'a'>>> v1Or using next, iter:
>>> k, v = next(iter(d.items()))>>> k'a'>>> v1>>>
