This looks better:
def setNested(nest, val):
el = nest.iterkeys().next()
if isinstance(nest[el], dict):
setNested(nest[el], val)
else:
nest[el] = val
return nest
But maybe something like this is closer to the OP needs:
def setNested(nest, path, val):
nest2 = nest
for key in path[:-1]:
nest2 = nest2[key]
nest2[path[-1]] = val
return nest
ndict = {'a1':{'b1':{'c1':1}, "b2":{"c2":2}}}
print ndict
print setNested(ndict, ("a1", "b1", "c1"), 3)
print setNested(ndict, ("a1", "b2", "c2"), 4)
Output:
{'a1': {'b1': {'c1': 1}, 'b2': {'c2': 2}}}
{'a1': {'b1': {'c1': 3}, 'b2': {'c2': 2}}}
{'a1': {'b1': {'c1': 3}, 'b2': {'c2': 4}}}
(But I don't like too much that kind of in place modify.)
