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()

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

从已经打开的cmd窗口或启动脚本 在Python 2中，在脚本的末尾添加如下内容:

 raw_input("Press enter to exit;")

或者，在Python 3中:

input("Press enter to exit;")

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.

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。

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。
