I have a dictionary in which each key is associated with a list as value.
eg: *dic={'a':['aa','ant','all']}*
The dictionary contains *1.5 lakh keys*.
Now i want to store it to a file,and need to be loaded to python program
during execution.
I expect your ideas/suggestions.
Note:I think cPickle,bsddb can be used for this purpose,but i want to
know
the best solution which runs *faster*.
Just try and see. You have to measure performance in your own specific use
case. What is best for others may not be the best for you; for example,
your dictionary appears to contain only strings, and this may affect
performance.
I would try:
cPickle with protocol=-1
a cPickle.Pickler object with protocol=-1 , also setting fast=1 in the
instance
the csv module
a SQL database, like sqlite
bsddb
a custom format, perhaps one word per line + blank line as separator.
But I would reconsider if having the whole dictionary in memory all the
time is a good idea. Databases are good for storing and retrieving
key->values.
