Methods
__init__
(**kwds)Initialize an ordered dictionary. clear
()copy
()fromkeys
(S[, v])If not specified, the value defaults to None. get
(k[,d])has_key
(k)items
()iteritems
()od.iteritems -> an iterator over the (key, value) pairs in od iterkeys
()itervalues
()od.itervalues -> an iterator over the values in od keys
()pop
(k[,d])value. popitem
()Pairs are returned in LIFO order if last is true or FIFO order if false. setdefault
(k[,d])update
([E, ]**F)If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v values
