Hi Steem! My name is ool. This is my first contact with this platform.
I know that there are many people who know technology.So I came here！
Share a great tool today, based on the python！
Tenacity is an Apache 2.0 licensed general-purpose retrying library, written in Python, to simplify the task of adding retry behavior to just about anything.
简单的来说 就是一个装饰器来完成处理异常并重试的功能
举个简单的例子如下:
import random
from tenacity import retry
@retry
def do_something_unreliable():
a = random.randint(0, 10)
print(a)
if a > 5:
raise IOError("Broken sauce, everything is hosed!!!111one")
else:
return "Awesome sauce!"
print(do_something_unreliable())
执行结果如下:
9
8
4
Awesome sauce!
上面的意思，就是 ，当随机的值大于5的时候发生异常，会继续执行这个函数，直到小于等于5的时候得到一个返回值。
有很多用途，比如写爬虫的时候，出现异常就会断掉 ，对程序的影响很大。有了这个类库就简单的多了
