Guesslang is an open source deep learning software that have been trained with over a million source code files.

You can use Guesslang as a command line interface tool or as a Python module:

from guesslang import Guess

guess = Guess()

# Guess the language from code
language = guess.language_name("""
    % Quick sort

    -module (recursion).
    -export ([qsort/1]).

    qsort([]) -> [];
    qsort([Pivot|T]) ->
           qsort([X || X <- T, X < Pivot])
           ++ [Pivot] ++
           qsort([X || X <- T, X >= Pivot]).
    """)

print(language)  # --> Erlang
