Dictionaries are string-indexed arrays. Section 15.4.2 shows how these data types are used.
#!/usr/bin/env python hsh = {} # create empty dicionary tel = {'jack': 4098, 'sape': 4139} tel['guido'] = 4127 print( tel) # -> {'sape': 4139, 'guido': 4127, 'jack': 4098} print( tel['jack']) # -> 4098 del tel['sape'] tel['irv'] = 4127 print( tel) # -> {'guido': 4127, 'irv': 4127, 'jack': 4098} print( tel.keys()) # -> ['jack', 'irv', 'guido'] print( tel.has_key('guido')) # -> True print( 'guido' in tel) # -> True
