The dictionary is the obvious way to index things:

# items consist of name and age
data = [
 ['fred', 42],
 ['jim', 16], ...
]

name_index = {}
for item in data:
 name_index[item[0]] = item

>>> name_index['fred']
['fred', 42]

Dictionaries are one of the most useful things in Python. Make sure you know
how to take adavantage of them...
