How do I build a tree dynamically in Python

Question

A beginner Python/programming question... I\'d like to build a tree structure in Python, preferably based on dictionaries. I found code that does this neatly:

Answer 1

This

root['toplevel']['secondlevel']['thirdlevel'] = 1

can also be done like this:

node = root
for key in ('toplevel', 'secondlevel'):
    node = node[key]
node['thirdlevel'] = 1

I hope that gives you an idea.
