我刚刚开始学习Python。当我在Windows上执行一个python脚本文件时,输出窗口出现但立即消失。我需要它停留在那里,这样我就可以分析我的输出。我怎么才能让它一直开着?

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.

试试这个,

import sys

stat='idlelib' in sys.modules

if stat==False:
    input()

这只会停止控制台窗口,而不是IDLE窗口。

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.

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。

`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()`

最简单的方法:

import time

#Your code here
time.sleep(60)
#end of code (and console shut down)

这将使代码保持1分钟,然后关闭它。
