Tas pats, kaip ir assoc. masyvas.

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can't use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

Žodyno pavyzdys

asmenys = { 'Jonas' : 'Jonaitis', 'Petras' : 'Petraitis', 'Vardenis' : 'Pavardenis' }
# Kokia Jono pavarde?
print asmenys['Jonas']
# Kokius vardus zhinome?
print asmenys.keys ()
# Du budai patikrinti, ar yra irashyta Petro pavarde
if (asmenys.has_key ('Petras')):
	print "Petras yra"
if ('Petras' in asmenys):
	print "Petras yra"

Žodyno darymas iš sąrašo/tuple'o

# Su dict() pasidarome zhodyna ish sarashu/tuples'u
print dict([('sape', 4139), ('guido', 4127), ('jack', 4098)]) # {'sape': 4139, 'jack': 4098, 'guido': 4127}
print dict([(x, x**2) for x in (2, 4, 6)]) # {2: 4, 4: 16, 6: 36}
