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!

	const lines = [
	'I am a string',
	'I am not a string',
	'Lies',
	'You got me',
	];

	function printLines(callback: () => void) {
	lines.forEach((line, i) => console.log(`Line ${i}: ${line}`));
	callback();

	from xml.dom.minidom import parse, parseString
	import urllib2
	# note - i convert it back into xml to pretty print it
	print parse(urllib2.urlopen("http://search.twitter.com/search.atom?&q=python")).toprettyxml(encoding="utf-8")

	def __iter__(self):
	for attr, value in self.__dict__.iteritems():
	yield (attr, value)
