The simplest use case is retrying a flaky function whenever an Exception occurs until a value is returned. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 import random from retrying import retry @retry def do_something_unreliable(): if random.randint(0, 10) > 1: raise IOError("Broken ...

一,retry模块 1,pip安装retry模块 1 pip install retry 2,retry介绍 1234567891011 def retry(exceptions=Exception, tries=-1, delay=0, max_delay=None, backoff=1, jit
这可以通过在 retry 修饰器中添加一个 retry_on_exception 函数来实现。 from retrying import retry def retry_if_io_error(exception): """Return True if we should retry (in this case when it's an IOError), False otherwise""" return isinstance(exception, IOError) @retry(retry_on_exception=ret...
wrap_exception 出现异常后返回的异常类型,True是返回原异常,False返回RetryError stop_func 自定义停止重试的条件,传入参数是一个函数 wait_func 自定义每次重试的时间间隔,传入参数是一个函数 wait_jitter_max 指定每次重试时间抖动值 stop 指定重试停止后,执行Retrying对象的成员函数 ...
import random from retrying import retry @retry def do_something_unreliable(): if random.randint(0, 10) > 1: print("just have a test") raise IOError("raise exception!") else: return "good job!" print(do_something_unreliable()) 运行这个程序,大家可以看到每次打印“just have a test”这...
1.python安装包出现WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) 就是国内因为源被限制,换源就可以了. pip3 config list pip3 config set global.index-url https:…
2^previous_attempt_number * wait_exponential_multiplier，previous_attempt_number是前⾯已经retry的次数，如果产⽣的这个值超过了wait_exponential_max的⼤⼩，那么之后两个retrying之间的停留值都为wait_exponential_max 我们可以指定要在出现哪些异常的时候再去retry，这个要⽤retry_on_exception传⼊⼀个...
