HELP! Simple question re: dictionaries

[emile at fenx.com]

Refer to key and value as key and value.  Each loop returns
a key value pair.  If the for loop was:

for k,v in my_dict.values():

you would use k and v to refer to the values.

To get a value from a dictionary, use:

value = my_dict[key]


Look on www.python.org for info.  There's plenty there.
