pyart.lazydict.MutableMapping.update

MutableMapping.update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does:

for k in E.keys(): 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
