One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

	# 30 minutes Lisp in Ruby
	# Hong Minhee <http://dahlia.kr/>
	#
	# This Lisp implementation does not provide a s-expression reader.
	# Instead, it uses Ruby syntax like following code:
	#
	# [:def, :factorial,
	# [:lambda, [:n],
	# [:if, [:"=", :n, 1],
	# 1,

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
