窗口立即打开和关闭

Question

我用Python 2.7编写了一个程序。 它在IDLE Shell中运行良好，但是当我尝试在Python命令行中打开它时，它会立即打开和关闭。 就像，在一瞬间。

请帮忙。

import socket
import time

TARGET_PROMPT = "What website do you want to find the IP address of?\n\n"

def ping():

    target = raw_input(TARGET_PROMPT)

    start = time.time()

    print("\nTrying to connect...")
    try:
        ip_address = socket.gethostbyname(target)

        end = time.time()
        connection_time = end - start

        print("Connection established.")
        print("IP address found: " + ip_address + "\n")
    except Exception as e:
        print("Connection failed.\n")


while True:
    ping()

编辑：我删除并重新安装了Python，现在看来工作正常。
