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 =

I found joblib is very useful with me. Please see following example:

from joblib import Parallel, delayed
def yourfunction(k):   
    s=3.14*k*k
    print "Area of a circle with a radius ", k, " is:", s

element_run = Parallel(n_jobs=-1)(delayed(yourfunction)(k) for k in range(1,10))

n_jobs=-1: use all available cores
