import time

# Decorator to calculate time taken by a function to run
def timeit(f):
    def timed(*args, **kw):
        ts = time.time()
        result = f(*args, **kw)
        te = time.time()
        print 'func:%r took: %2.4f sec' % \
          (f.__name__, te-ts)
        return result
    return timed

@timeit
def sayhi(name):
    print "Hi {}".format(name)
    time.sleep(2)

sayhi("Aayush")
