New submission from ndbecker <ndbeck...@gmail.com>:
from multiprocessing import Pool
def power (x, pwr=2):
return x**pwr
import functools
run_test = functools.partial (power, pwr=3)
if __name__ == "__main__":
pool = Pool()
cases = [3,4,5]
results = pool.map (run_test, cases)
TypeError: type 'partial' takes at least one argument
