This is almost exactly what the "dbm" (nee "anydbm") module does, but
persisting the dictionary out to the disk:
import dbm
from sys import argv
with dbm.open("my_cache", "c") as db:
if len(argv) > 1:
key = argv[1]
if key in db:
print("Found it:", db[key])
else:
print("Not found. Adding")
if len(argv) > 2:
value = argv[2]
else:
value = key
db[key] = value
else:
print("There are %i items in the cache" % len(db))
The resulting "db" acts like a dictionary, but persists.
If you really must have the results as a "real" dict, you can do the
conversion:
real_dict = dict(db)
-tkc
