[Tutor] Accessing Specific Dictionary items
Hi all,
I'm trying to access and use specific items within a dictionary that
is returned but am having issues in doing so.
[{'city': 'Sunnyvale', 'region_name': 'CA', 'area_code': 408,
'metro_code': 'Santa Clara, CA', 'country_name': 'United States'}]
How can I populate a list of many different returns so that I have a
list that contains all the cities and in line with the item that is
referenced.
The first step is to populate the list unsorted as it needs to be in
correlation to the item that it came from.
Thanks for your help.

Re: [Tutor] Accessing Specific Dictionary items
I'm not sure I'm following. Could you give an example of expected input and
expected output?

Could you give us examples of what you want the list to look like? It
will help us direct you to an answer.

Re: [Tutor] Accessing Specific Dictionary items
The input being used is through pygeoip.
Using this I am pulling the data by IP and from what I am reading this
populates as a dictionary.
Here is some of the output that I can show currently
[{'city': 'Buena Park', 'region_name': 'CA', 'area_code': 714},
{'city': 'Wallingford', 'region_name': 'CT', 'area_code': 203},
{'city': 'Schenectady', 'region_name': 'NY', 'area_code': 518},
{'city': 'Athens', 'region_name': '35'}]
I'd like to have an output similar to this:
'Buena Park', 'Wallingford', 'Schenectady','Athens' pulled by the
city keys that are used in the returns. I think the easiest way to
approach this would be simply to use the .append and populate a list
but I don't know how to pull an item by key value from the dictionary
returns.
I hope this helps clear some confusion and thanks in advance.

What do you mean, the returns?
If all you want is a list of cities, that's easy:
cities = [d['city'] for d in list_of_dicts]
or if you prefer a more verbose way:
cities = []
for d in list_of_dicts:
cities.append(d['city'])
To get the list sorted, just sort it afterwards:
cities.sort()
I think the easiest way to
approach this would be simply to use the .append and populate a list
but I don't know how to pull an item by key value from the dictionary
returns.
The same way you would pull an item by key from any other dict.

Re: [Tutor] Accessing Specific Dictionary items
Dictionaries are objects and you access their attributes through keys.
So, let's say I had a dict: d = {'city':'plattsburgh'}
I would thus access the attribute by doing this
d['city']
You can store that value to a variable
Or you can append to a list directly.
l = []
for d in yourdict:
l.append(d['city'])

Re: [Tutor] Accessing Specific Dictionary items
Thank you all, I have found the assistance needed and the guidance
here was wonderful.
I needed to add a line in the middle that did a temporary storage for
me before trying to append this to the list. It might not be the most
elegant solution but it works.

IMHO this is overkill.
Consider instead using City-Region as the key and storing the pther
attributes in a tuple. There is no need to have separate dictionaries or
lots of repetitive keys:
cities = {
'Buena Park CA': (414, 'Santa Clara, CA'),
'Wallingford'CT: (203),...}
