To create a dict:

d = { 'key1' : 'value1',  'key2' : 'value2' }

d['key1']       # evaluates to 'value1'
d['key2']       # evaluates to 'value2'
d['test']         # raises a KeyError exception

Please also note that a dictionary is an object, it has many methods 
like d.keys, d.values, d.has_key etc.
There is no array type in Python but there are higher level data 
structures: list, tuple, dictionary and set.

It seems you have not read the tutorial, did you?
