Python's time.clock() vs. time.time() accuracy?

Question

Which is better to use for timing in Python? time.clock() or time.time()? Which one provides more accuracy?

for example:

start = time.clock()
... do          


        

Answer 1

I use this code to compare 2 methods .My OS is windows 8 , processor core i5 , RAM 4GB

import time

def t_time():
    start=time.time()
    time.sleep(0.1)
    return (time.time()-start)


def t_clock():
    start=time.clock()
    time.sleep(0.1)
    return (time.clock()-start)




counter_time=0
counter_clock=0

for i in range(1,100):
    counter_time += t_time()

    for i in range(1,100):
        counter_clock += t_clock()

print "time() =",counter_time/100
print "clock() =",counter_clock/100

output:

time() = 0.0993799996376

clock() = 0.0993572257367
