What sort of data do you expect to store in the dictionary?

The only thing I can think of is "address" and "coordinates". As you say below,
there is code to convert an address to its latitude and longitude, so you can
map address to coordinates:

d = {}
for address in list_of_addresses:
     coord = get_coordinates_from_address(address)  # whatever that function is
     d[address] = coord

But I don't think this is useful. What do you intend to do with the addresses,
and why do you think a dictionary is where you want to store them?

This isn't really a Python question. The answer depends on the features that
Google provides via their Maps API. See here to get started:
