Sorting dicts inside dicts

[abhijeet thatte]

Hi,
I have a huge dict structure like below:
*
{'module':{'reg_dict_0':{'name':'abc','reg_addr':'2004'},'reg_dict_1':{'name':'xyz','reg_addr':'2002'},'reg_dict_2':{'name':'pqr','reg_addr':'2008'}}
*

Module dict and reg_dicts contain many elements than shown.

I want to sort this 'module' dictionary as per 'reg_addr' element in every
'reg_dict'.

There is no relation between 'reg_dict' suffix and address. So, reg_dict_0
can contain reg_address = 2000/72 (any number)
I do not want output in a list format as the actual dict size is huge which
I want to use based on key value pair.

So, I want output as :

*
{'module':{'reg_dict_1':{'name':'xyz','reg_addr':'2002'},'reg_dict_0':{'name':'abc','reg_addr':'2004'},'reg_dict_2':{'name':'pqr','reg_addr':'2008'}}
*
*
*

Is it possible to sort the things? What I guess is Python stores dicts in a
tree like structure but I am forcing it to store the way I want. Is it
possible  to do something like that.

Thanks,
