使用timeit进行性能测试

def timeit(stmt="pass", setup="pass", timer=default_timer,
           number=default_number, globals=None):
    """Convenience function to create Timer object and call timeit method."""
    return Timer(stmt, setup, timer, globals).timeit(number)

def repeat(stmt="pass", setup="pass", timer=default_timer,
           repeat=default_repeat, number=default_number, globals=None):
    """Convenience function to create Timer object and call repeat method."""
    return Timer(stmt, setup, timer, globals).repeat(repeat, number)

两个都是生成了timer对象，然后调用timeit or repeat方法

其中如果setup为复合语句，则用 ; 隔开

import timeit

t = timeit.Timer("r.get('123')","import redis;pool = redis.ConnectionPool(host='127.0.0.1', port=6379, decode_responses=True);r = redis.Redis(connection_pool=pool)")

#使用分号对于多个
t.timeit(100)
