plotly: List of valid country names from ISO-3 code

Question

In Python, I'm plotting a choropleth with some data for some countries in Africa:

countries = ['BDI', 'BEN', 'BFA', 'BWA', 'CIV', 'CMR', 'COD', 'CPV', 'ETH', 'GHA', 'GIN', 'GMB', 'KEN', 'LBR', 'LSO', 'MDG', 'MLI', 'MOZ', 'MUS', 'MWI', 'NER', 'NGA', 'RWA', 'SEN', 'SLE', 'SOM', 'STP', 'TCD', 'TGO', 'TZA', 'UGA', 'ZAF', 'ZMB', 'ZWE']
z = [5, 6, 1, 1, 2, 14, 7, 1, 3, 6, 1, 2, 13, 1, 3, 11, 4, 2, 1, 6, 1, 50, 18, 5, 2, 4, 1, 1, 4, 16, 15, 4, 10, 4]

Plotting this data like so:

import plotly.offline as py
import plotly.graph_objs as go

countries = ['BDI', 'BEN', 'BFA', 'BWA', 'CIV', 'CMR', 'COD', 'CPV', 'ETH', 'GHA', 'GIN', 'GMB', 'KEN', 'LBR', 'LSO', 'MDG', 'MLI', 'MOZ', 'MUS', 'MWI', 'NER', 'NGA', 'RWA', 'SEN', 'SLE', 'SOM', 'STP', 'TCD', 'TGO', 'TZA', 'UGA', 'ZAF', 'ZMB', 'ZWE']
z = [5, 6, 1, 1, 2, 14, 7, 1, 3, 6, 1, 2, 13, 1, 3, 11, 4, 2, 1, 6, 1, 50, 18, 5, 2, 4, 1, 1, 4, 16, 15, 4, 10, 4]

layout = dict(geo={'scope': 'africa'})
data = dict(
    type='choropleth',
    locations=countries,
    locationmode='ISO-3',
    colorscale='Viridis',
    z=z)
map = go.Figure(data=[data], layout=layout)
py.plot(map)

Output is an interactive map with the z value and ISO-3 code displayed when you hover over.

Intended output: I would like to have the country's name displayed rather than ISO-3 code. I suppose this can be done by passing in the countries' names as the locations and setting locationmode to 'country names'.

Is there a mapping from ISO to country name for the purposes of this? A list/dict/DataFrame of corresponding values within the plotly config, for example? I've had a look but can't find anything.

Thank you

We converted the country name by referring to a two-letter abbreviation from a three-letter abbreviation. The site from which the data was referenced is the following

Country ISO Codes -> Country Names

c_names = []
for c in countries:
    for c2,c3 in iso3.items():
        if c3 == c:
            for v2,v3 in names.items():
                if c2 == v2:
                    c_names.append(v3)

c_names
['Burundi',
 'Benin',
 'Burkina Faso',
 'Botswana',
 'Ivory Coast',
 'Cameroon',
 'Democratic Republic of the Congo',
 'Cape Verde',
 'Ethiopia',
 'Ghana',
