如何从元组中ping？

Question

如何从元组中ping主机列表并将响应存储到另一个元组列表中？

我知道如何ping单个主机：

hostname = "10.0.0.250" #example

response = os.system("ping -c 1 " + hostname)

Answer 1

在给定主机名元组的情况下，你可以简单地使用列表理解 / 生成器表达式（用于元组）：

hostnames = ("10.0.0.250", "10.0.0.240", ...)
responses = tuple(os.system("ping -c 1 " + h) for h in hostnames)

Answer 2

hostnames = ["10.0.0.1", "10.0.0.2"]
# Can use a tuple instead of list.
responses = [os.system("ping -c 1 " + hostname) for hostname in hostnames]
# You can enwrap the list comprehension in a call to the tuple() function
# to make `responses` a tuple instead of list.
