How do I parallelize a simple Python loop?

Question

This is probably a trivial question, but how do I parallelize the following loop in python?

# setup output lists
output1 = list()
output2 = list()
output3 =

thanks @iuryxavier

from multiprocessing import Pool
from multiprocessing import cpu_count


def add_1(x):
    return x + 1

if __name__ == "__main__":
    pool = Pool(cpu_count())
    results = pool.map(add_1, range(10**12))
    pool.close()  # 'TERM'
    pool.join()   # 'KILL'
