Question

我想要两个脚本在python中进行通信。我希望他们知道其他人是否失败了。

按照你在图片中看到的内容我有一些问题。当我运行rob2.py时，我会自动运行rob1.py，为什么会这样？

rob1.py

import simpy
import time
from rob2 import brok2

class Moving:
    def __init__(self, env):
        self.env = env
        """What does self.prov do?"""
        self.prov = env.process(self.work())
        self.broken = False
        if self.broken == False:
            global brok1
            brok1 = 0
        else:
            brok1 = 0
        #print(brok1)
    def work(self):
        while True:
            yield env.timeout(20)


if brok2 == 1:
    print("Robot 2 is not broken")
else:
    print("Robot 2 is broken")
env= simpy.Environment()
moving = Moving(env)
env.run(until = 60)

rob2.py

import simpy
import time
from rob1 import brok1

class Placing:

    def __init__(self, env):
        self.env = env
        """What does self.prov do?"""
        self.prov = env.process(self.work())
        self.broken = False
        if self.broken == False:
            global brok2
            brok2=1
        else:
            brok2 = 0

    def work(self):
        while True:
            yield env.timeout(20)

time.sleep(5)
if brok1 == 1:
    print("Robot 1 is not broken")
else:
    print("Robot 1 is broken")
env= simpy.Environment()
placing = Placing(env)
env.run(until = 60)

当我收到尝试运行脚本的消息时，我做错了什么？

Traceback (most recent call last):
  File "rob2.py", line 3, in <module>
    from rob1 import brok1
  File "/Users/erik/Python/python/rob1.py", line 3, in <module>
    from rob2 import brok2
  File "/Users/erik/Python/python/rob2.py", line 3, in <module>
    from rob1 import brok1
ImportError: cannot import name 'brok1'

我发现了一些关于zeroMQ的帖子，那是去这里的方式吗？

抛出ImportError异常，因为Python检测到循环导入循环：在你的一个文件中导入另一个，它自己导入第一个，导入第二个，依此类推。

您需要重新组织代码以避免这种情况。大多数（所有？）编程语言都不喜欢循环导入。

尝试使用Python
