What is the proper way to delete selected items during iteration of a
map? What I want to do is:
for (k, v) in m.items():
if f(k):
# do some processing of v and save result elsewhere
del m[k]
But this gives (as should be expected):
RuntimeError: dictionary changed size during iteration
In the past I've accumulated the keys to be deleted in a separate list,
but this time there are likely to be a large number of them, so is there
some better way?
