提高python性能之绑定方法

import time
class Test():
def m(self, n):
return n
test = Test()
t1 = 0
f = test.m
for j in xrange(10):
sum = 0
t = time.time()
for i in xrange(1000000):
sum += f(i)
t1 += time.time() - t
t2 = 0
for j in xrange(10):
sum = 0
t = time.time()
for i in xrange(1000000):
sum += test.m(i)
t2 += time.time() - t
print t1 /10
print t2 /10
print (t2 - t1) / t2 * 100, '%'


　　结果：



0.85
1.00780000687
15.6578691994 %
　　性能相差15％!看来python有绑定方法还是挺不错的!
