Simple example using numba.

NumbaTemplate.py

from numba import jit
import numpy as np
from timeit import timeit

x = np.random.rand(100000)

@jit
def myfunc(x):
    for i in range(len(x)-1):
        x[i] **= x[i+1]

myfunc(x)

n = 10
print timeit(stmt='myfunc(x)', setup='from __main__ import myfunc, x', number=n)/n




def myfunc2(x):
    for i in range(len(x)-1):
        x[i] **= x[i+1]

try:
	myfunc2_fast = jit()(myfunc2)
except:
	myfunc2_fast = myfunct2
          
print timeit(stmt='myfunc2(x)', setup='from __main__ import myfunc2, x', number=n)/n

print 'Done'
