Python list help (incrementing count, appending)

Question

I am trying to connect google\'s geocode api and github api to parse user\'s location and create a list out of it.

The array (list) I want to create is like this:

Answer 1

This would be better stored as a dictionary, indexed by city name. You could store it as two dictionaries, one dictionary of tuples for latitude/longitude (since lat/long never changes):

lat_long_dict = {}
lat_long_dict["San Francisco"] = (x, y)
lat_long_dict["Mumbai"] = (x1, y1)

And a collections.defaultdict for the count, so that it always starts at 0:

import collections
city_counts = collections.defaultdict(int)

city_counts["San Francisco"] += 1
city_counts["Mumbai"] += 1
city_counts["San Francisco"] += 1
# city counts would be
# defaultdict(, {'San Francisco': 2, 'Mumbai': 1})
