JavaScript-like object in python

d

class D(dict):
	def __init__(self):
		dict.__init__(self)
		
	def __getitem__(self, key):
		val = D()
		try:
			val = dict.__getitem__(self, key)
		except:
			dict.__setitem__(self, key, val)
		return val
		
	def __setitem__(self, key, val):
		dict.__setitem__(self, key, val)

#I like JavaScript object. So I did this.
#try this
#> a = D()
#> a[1][2][3] = 4

Isn't line 6 supposed to be val = D()?

@fajran yeah... I changed the name and forgot that. edited, thx

Have you tried using defaultdict?

from collections import defaultdict
D=lambda : defaultdict(D)
