Inserting in multidimension dictionary.

[bharathpaul]

I am working with python 3.1.1 Below is my code and this works well.

dict={'paul':{'age':23,'hobby':'computer','like':'music'}}
print (dict['paul']['hobby'])

But how to insert a new item in the above dictionary.
If i tried with, say
dict['anotheritem']['nested']='true' , it gives error...
Also help me in printing the elements using Loop

Hi

There may be a better way to do this, but in general I've always added the outer dictionary and then populated it.

(BTW better not to use dict, since it's taken! I've changed it to myDict below)

myDict['anotheritem']=dict() #creates empty dictionary
myDict['anotheritem']['nested']=True #populated new dictionary

Regarding the printing:

for d1 in myDict:
    for d2 in myDict[d1]:
        print d1, d2, myDict[d2]

should work (ie I haven't tried it out)

Good luck, and please post back to tell us how it goes...

Thanks. Its working. But to print, its not working.so i've used the below code to print

mydict=dict()
mydict['a']=dict()
mydict['a']['nested']=True
for key1,value1 in mydict.items():
    tempdict = dict(mydict[key1].items())
    for key,value in tempdict.items():
       print (key1,key,value)

And This is working good....
Thanks once again

Oh, sorry. This is what you get when you don't run the code. It should be:

for d1 in myDict:
    for d2 in myDict[d1]:
        print d1, d2, myDict[d1][d2]
 

But you got the idea, and solved it yourself, which is great!
