Yeah your code may be from google but you have renamed something.

All your calls need to go though the YouTube serivce object

 youtube = googleapiclient.discovery.build(
        api_service_name, api_version, credentials=credentials)

Yet you are calling it using api

request = api.youtube.search().list(

it should be

request = youtube.search().list(

Check the code from google again and becameful when you rename things if you don't understand what there used for.

        client_secrets_file, scopes)
    credentials = flow.run_console()
    youtube = googleapiclient.discovery.build(
        api_service_name, api_version, credentials=credentials)

Error number 2

You need to check the parameters you are sending remove location thats not a valid location
