Python等待100秒并返回True或False

Question

I have python script below, which checks whether ping is success, If it success within 100 Seconds it will return True. If ping is failed it should return False but it is not returning False and when ping is success it is returning True.

Can anyone fix below code why it is not return False

Code:

def ping(self,hostname):
        time_check = datetime.now()
        data = ""
        while not "Success" in data:
            time.sleep(1)
            data = self.pingCheck("ping 10.10.10.1 count 5")
            if (datetime.now()-time_check).seconds > 100:
                return False
        return True

Answer 1

The code below will work for you:

import time

def ping(self, hostname, try_for=100):
    t_end = time.time() + try_for
    is_succeed = False
    while time.time() < t_end or is_succeed:
        time.sleep(1)
        data = self.pingCheck("ping 10.10.10.1 count 5")
        is_succeed = "Success" in data
    return is_succeed

I've defined wait time as parameter called try_for , which default value is set to 100 , but you can pass any other amount of seconds which you want spend waiting for host availability.
