converting a 2d dictionary to a numpy matrix

Question

I have a huge dictionary something like this:

d[id1][id2] = value

example:

books[\"auth1\"][\"humor\"] = 20
books[\"auth1\"         


        

Answer 1

pandas do this very well:

books = {}
books["auth1"] = {}
books["auth2"] = {}
books["auth1"]["humor"] = 20
books["auth1"]["action"] = 30
books["auth2"]["comedy"] = 20

from pandas import *

df = DataFrame(books).T.fillna(0)

The output is:

       action  comedy  humor
auth1      30       0     20
auth2       0      20      0
