Go here and download and install Notepad++ Go here and download and install Python 2.7 not 3. Start, Run Powershell. Enter the following. [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User") Close Powershell and reopen it. Make a directory for your programs. mkdir scripts Open that directory cd scripts In Notepad++, in a new file type: print "hello world" Save the file as hello.py Go back to powershell and make sure you are in the right directory by typing dir. You should see your file hello.py there. At the Powershell prompt type: python hello.py

在python 2中，你可以使用:raw_input()

>>print("Hello World!")    
>>raw_input('Waiting a key...')

在python 3中，你可以使用:input()

>>print("Hello world!")    
>>input('Waiting a key...')

你也可以用时间。sleep(time)

>>import time
>>print("The program will close in 5 seconds")
>>time.sleep(5)

你有几个选择:

Run the program from an already-open terminal. Open a command prompt and type: python myscript.py For that to work you need the python executable in your path. Just check on how to edit environment variables on Windows, and add C:\PYTHON26 (or whatever directory you installed python to). When the program ends, it'll drop you back to the cmd prompt instead of closing the window. Add code to wait at the end of your script. For Python2, adding ... raw_input() ... at the end of the script makes it wait for the Enter key. That method is annoying because you have to modify the script, and have to remember removing it when you're done. Specially annoying when testing other people's scripts. For Python3, use input(). Use an editor that pauses for you. Some editors prepared for python will automatically pause for you after execution. Other editors allow you to configure the command line it uses to run your program. I find it particularly useful to configure it as "python -i myscript.py" when running. That drops you to a python shell after the end of the program, with the program environment loaded, so you may further play with the variables and call functions and methods.

在出现异常时保持窗口打开(打印异常时)

Python 2

if __name__ == '__main__':
    try:
        ## your code, typically one function call
    except Exception:
        import sys
        print sys.exc_info()[0]
        import traceback
        print traceback.format_exc()
        print "Press Enter to continue ..." 
        raw_input() 

在任何情况下保持窗户开着:

if __name__ == '__main__':
    try:
        ## your code, typically one function call
    except Exception:
        import sys
        print sys.exc_info()[0]
        import traceback
        print traceback.format_exc()
    finally:
        print "Press Enter to continue ..." 
        raw_input()

Python 3

对于Python3，你必须使用input()来代替raw_input()，当然还要调整print语句。

if __name__ == '__main__':
    try:
        ## your code, typically one function call
    except BaseException:
        import sys
        print(sys.exc_info()[0])
        import traceback
        print(traceback.format_exc())
        print("Press Enter to continue ...")
        input() 

在任何情况下保持窗户开着:

if __name__ == '__main__':
    try:
        ## your code, typically one function call
except BaseException:
    import sys
    print(sys.exc_info()[0])
    import traceback
    print(traceback.format_exc())
finally:
    print("Press Enter to continue ...")
    input()

使用atexit，你可以在程序退出时暂停它。如果一个错误/异常是退出的原因，它将在打印堆栈跟踪后暂停。

import atexit

# Python 2 should use `raw_input` instead of `input`
atexit.register(input, 'Press Enter to continue...')

在我的程序中，我调用了atexit。在except子句中注册，这样它只会在出现错误时暂停。

if __name__ == "__main__":
    try:
        something_that_may_fail()

    except:
        # Register the pause.
        import atexit
        atexit.register(input, 'Press Enter to continue...')

        raise # Reraise the exception.

cmd /k是打开任何控制台应用程序(不仅仅是Python)的典型方式，其中控制台窗口在应用程序关闭后仍然存在。我能想到的最简单的方法是按下Win+R，键入cmd /k，然后拖放你想要的脚本到运行对话框。
