Need to return all the values of a key from the api response using python-CodePudding

I am trying to list the values of country from the api response. While I tired it is throwing an error as TypeError: list indices must be integers or slices, not str

import requests
response = requests.get("https://countriesnow.space/api/v0.1/countries")
json_response = response.json()
# dictionary = json.dumps(response.json(), sort_keys = True, indent = 4)

country_name = json_response['data']['country']

I have taken the api endpoint from the browser where i need to list out the country values and check whether the data i extracted as text matches the country values present in the api endpoint.

Can you please let me know where I am using doing the mistake, as i was stuck on this for past wo days.

When I give it as

country_name = json_response['data'][0]['country']

the first country name is getting printed but i need all the values of country.

CodePudding user response：

Loop through the data list items and pick the value with key country and append to the list

countries = []
for country in json_response['data']:
    countries.append(country['country'])
print(countries)

Another method using list comprehension:

countries = [json_response['data'][i]['country'] for i in range(len(json_response['data']))]

CodePudding user response：

You need to iterate over everything in the list json_response['data'] and pull out country:

countries = [json_response['data'][i]['country'] for i in len(json_response['data'])]

CodePudding user response：

Your response data is a nested list. You need to loop through it to retrieve all values:

countries = [x['country'] for x in json_response['data']]
# or
countries = list(map(lambda x: x['country'], json_response['data']))

CodePudding user response：

The reason why country_name = json_response['data']['country'] breaks is that json_response['data'] gives you a list which can only be indexed by int or numbers hence the error TypeError: list indices must be integers or slices, not str.

here is a much simpler version of what they're trying to do

countries = []
for country in json_response["data"]:
    countries.append(country["country"])

print(countries)
