Converting data into dictionary of Dictionaries in python

Question

I am reading a file in python using a key value pair, for example

Mac:aaaa
IP:bbbbb
Name:dddd

Mac:wwwww
IP:fffff
Name:sssss

Mac:hhhh
IP:ddd
Name:fff

so, my query is, I need to build a dictionary of dictionaries for the above data so as to format it as json.

Answer 1

I assume you mean a list of dictionaries, not a dictionary of dictionaries

from operator  import methodcaller
fdata = open("data.txt").read().split()
split2 = methodcaller("split",":")
print map(dict, zip(*[iter(map(split2, fdata))]*3))

is a fun way to do it ;)

however if you did want a dictionary of dictionaries as your title suggests you can simply

dict(enumerate(map(dict, zip(*[iter(map(split2, fdata.split()))]*3))))
