`import sys,traceback
sys.exc_info()[0]
traceback.format_exc()
print("Press Enter to exit ...")
input()`

只需在实际代码之后编写上面的代码。如。我从用户输入和打印在控制台，因此我的代码将看起来像这样->

`import sys,traceback
nam=input("enter your name:")
print("your name is:-{}".format(nam)) #here all my actual working is done
sys.exc_info()[0]
traceback.format_exc()
print("Press Enter to exit ...")
input()`

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()

除了input和raw_input，你还可以使用一个无限while循环，像这样: while True: pass (Python 2.5+/3)或while 1: pass(所有版本的Python 2/3)。不过，这可能需要计算能力。

还可以从命令行运行程序。在命令行中输入python (Mac OS X终端)，它应该是python 3。(你的Python版本)如果它没有显示你的Python版本，或者说Python:命令没有找到，查看更改PATH值(环境值，上面列出)/输入C:\(Python文件夹\ Python .exe。如果成功，输入python或C:\(python安装)\python.exe和程序的完整目录。

我也遇到过类似的问题。在notepad++中，我曾经使用命令:C:\Python27\python.exe "$(FULL_CURRENT_PATH)"在代码终止后立即关闭cmd窗口。 现在我使用cmd /k c:\Python27\python.exe "$(FULL_CURRENT_PATH)"它保持cmd窗口打开。

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.
