Python syntax error while taking an IP address as an input (2 个回答)

已关闭 7 年前。

我正在尝试 ping 应用程序运行后输入的特定 IP 地址。这是我当前的代码，但每次我输入 IP 时，都会出现错误，指出语法无效。我搜索过其他主题，但它们涉及同时 ping 一系列 IP。感谢您的帮助。

def pingComputer():
import os
hostname = input("Enter the ip address: ")
response = os.system("ping -c 1 " + hostname)

if response == 0:
    print hostname, 'is up!'
else:
    print hostname, 'is down!'

Answer 1

相关代码存在一些问题，但这里是一个更接近工作版本的版本:

# put the imports here for better readability.
import os

def pingComputer():
    # you need to indent when you write code for a function
    # you also need to use raw_input in python 2.x because raw_input returns a string
    # where input tries to interpret the input.
    hostname = raw_input("Enter the ip address: ")
    response = os.system("ping -c 1 " + hostname)

    if response == 0:
        print hostname, 'is up!'
    else:
        print hostname, 'is down!'

# you weren't calling your function,
# I added a standard main check which will call your function.
if __name__ == "__main__":
    pingComputer()
