Window Opens and Closes Immediately

Question

I wrote a program in Python 2.7. It's working great in the IDLE Shell, but when I try to open it in the Python Command Line, it open and closes immediately. Like, in a split second.

Please help.

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()

Edit: I deleted and reinstalled Python, and now it seems to be working fine.

And how exactly are you opening it in the Python command line? — martineau, Nov 11 '17 at 03:21
@martineau I'm simply finding the Python file in File Explorer and double-clicking on it. — Owen Strand, Nov 11 '17 at 03:22
Hold down shift and right click somewhere in that folder. Click "open command prompt here" then type "python your_file_name.py". — roganjosh, Nov 11 '17 at 03:24
That's not opening it from the Python command line. That's running it from Explorer. Run it from the Windows command line with `python myscript.py` (or maybe `python3 myscript.py`). — martineau, Nov 11 '17 at 03:25
@martineau I got this: 'python' is not recognized as an internal or external command, operable program or batch file. — Owen Strand, Nov 11 '17 at 03:26
@roganjosh Command Prompt didn't open. Windows Powershell did. And it didn't recognize the file. — Owen Strand, Nov 11 '17 at 03:27
you need to add c:\Python27 to your path ... you will need to google to learn how — Joran Beasley, Nov 11 '17 at 03:27
Ok interesting, i dont know why that gave you Powershell. How did you install python and what version? — roganjosh, Nov 11 '17 at 03:28
The programme is working fine. Fix your environment variable and try again. Check [this](https://stackoverflow.com/questions/3701646/how-to-add-to-the-pythonpath-in-windows-7) to know how to set the environment variable for python. — Vipin Yadav, Nov 11 '17 at 03:29
@roganjosh The normal way: with python.org. It's version 2.7.14. And, some of my Python files are working, and some are not. — Owen Strand, Nov 11 '17 at 03:30
If you use the Python installer, it should have asked you if you wanted Python added to your path. Sounds like that didn't happen for some reason. You can do it manually by editing your system environment variables and adding a path to `python.exe` to the existing `PATH` variable. I think this is done by editing your computer's "Properities". — martineau, Nov 11 '17 at 03:32
