class OrderedSet(*collections)

Ordered set based on uniqueness of dictionary keys.

Initialize self. See help(type(self)) for accurate signature.

update(*args)

D.update([E, ]**F) -> None. Update D from dict/iterable E and F. If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
