append into json

[luisbatalla]

Try to implement the following algorithm:

1) parse json-string to Python dictionary (use json module to do this);
2) modify the dictionary you got at #1;
3) convert the dictionary to json-string (json module);

But how I cand append? Could you help me with an example ? I should append into "Element" tag
Thank in advance!
