Python configure dict structure

Question

Is there a way to save a python dict structure in config then access it?

For example:

dict = {'root': {'category': {'item': 'test'}}}

# in my config
key = 'some string here'

print (dict[key])

# output
>> test

Solution thanks to answers below:

from functools import reduce
import json

dict = {'root': {'category': {'item': 'test'}}}

# you can put this in your config.ini file
map = '["root", "category", "item"]'

print (reduce(lambda d, k: d[k], json.loads(map), dict))

#output
test

Answer 1

尝试使用reduce()函数或pickle协议

Answer 2

Just use the pickle protocol. You can store virtually anything using that. documentation on pickling: http://docs.python.org/2/library/pickle.html
