A note on terminology: the things inside curly brackets {} are called
dictionaries, or dicts, not directories. And the things you use to store
data in dictionaries are called keys, not indexes:
# Lists have indexes:
L = ['x', 'y', 'z']
L[0] # returns the item in position 0
# Dicts have keys:
D = {'a': 'x', 2: 'y', 7.8: 'z'}
D['a'] # returns the item with key 'a'
