how can I use youtube API to search channels by country?

I want to search Youtube channels and filter them by the user's country among other stuff How can i do that ?

I never dealt with an A开发者_Python百科PI before , so it would be useful to direct me which language should I use and some tutorials on youtube APIs other than Google's.

you can use the api in different languages , you should go through developers API here , It has all details,

http://code.google.com/apis/youtube/2.0/reference.html

search appropriate URL according to your needs.
