Python坚韧:如果所有重试都失败了，我如何重试一个函数而不引发异常？

import time

def retry_function(func, max_retries=3, delay=1):
    retries = 0
    while retries < max_retries:
        try:
            result = func()  # 调用需要重试的函数
            return result
        except Exception as e:
            print(f"Exception caught: {e}")
            retries += 1
            time.sleep(delay)  # 延迟一段时间后再次尝试
    raise Exception("All retries failed")  # 所有重试都失败，抛出异常

# 示例函数，模拟一个可能会引发异常的函数
def my_function():
    if time.time() % 2 == 0:
        return "Success"
    else:
        raise Exception("Random exception")

result = retry_function(my_function)
print(result)
