List of language codes (ISO639-1) in Python?

Question

Is it possible to get the list of all ISO639-1 language codes from pycountry 1.15? For example, ['en','it','el','fr',...]? If yes then how?

The following doesn't work I am afraid:

import pycountry
pycountry.languages

Answer 1

This will give you a list of two-digit ISO3166-1 country codes:

countries = [country.alpha2 for country in pycountry.countries]
#countries = [country.alpha_2 for country in pycountry.countries]  # for python3 

This will give you a list of two-digit ISO639-1 language codes:

langs = [lang.iso639_1_code
         for lang in pycountry.languages
         if hasattr(lang, 'iso639_1_code')]

This will give you a list of all of the language codes:

langs = [getattr(lang, 'iso639_1_code', None) or 
         getattr(lang, 'iso639_2T_code', None) or 
         getattr(lang, 'iso639_3_code') 
         for lang in pycountry.languages]
