def iterate(data, indentation):
	if isinstance(data, dict):
		for key, value in data:
			print(key)
			if is_iterable(value):
				iterate(value, indentation+indent)
			else:
				pass

from collections import Iterable

def is_iterable(data):
	if isinstance(value, Iterable):
		return True
	else:
		return False
