How to convert coordinates or addresses to ISO 3166 codes

while trying to analyse some data i ran into a problem where i am supposed to convert some locations to their iso3166 equivalence so as to make a need Choropleth map of the data but converting the data has seem to be a hassle sorry that i have not shown my trial solution.

here is the data set

        Location                                            Organisation

I am hoping to get something like this below. its the first four rows of the above dataset

        Location      Organisation
0   USA             1
1   FRA             78
2   FRA                 15
3   FRA             1

though i noticed most of the addresses ended with their iso3166 representations i tried this

for data in df_data.Location:
    df_data.Location = df_data.Location[-1:]

i was aiming to get the last word which i hoped it would be the iso3166 which it was not and beside the code kept returning df_data.Location.values as "NAN"

Let's take a simplified version of the data you have:

df = pd.DataFrame({
    'location': ['ELA-3, Guiana Space Centre, French Guiana, France',
                 'ELS, Guiana Space Centre, French Guiana, France', 
                 'LA-Y1, Tanegashima Space Center, Japan',
                 'LC-2, Xichang Satellite Launch Center, China'],
    'organization': [78, 2, 29, 35]
})

df

Output:

Then:

df["Country"] = df["location"].map(lambda x: x.split(",")[-1])
df

Output:
