    How you do this in a practic way without
    the use of one-line code ?

the OPs code contains five reads and three writes, my and
steven's versions contain four reads and three writes.  the
yet-to-be-released ternary operator would remove one read
from the OPs code, which makes both alternatives equivalent.

dictionary accesses don't involve passes over the dictionary.

there's a comment on readability and code understanding waiting
to be made here, but I'll leave that for another day.
