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?

如果你想保持cmd-window打开并且在运行文件目录下,这在Windows 10下是有效的:

cmd /k cd /d $(CURRENT_DIRECTORY) && python $(FULL_CURRENT_PATH)

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。

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.

为了保持窗口打开,我同意Anurag的观点,这就是我为简短的计算类型程序保持窗口打开所做的。

这只会显示一个没有文本的游标:

raw_input() 

下一个例子会给你一个明确的消息,程序已经完成,而不是等待程序内的另一个输入提示:

print('You have reached the end and the "raw_input()" function is keeping the window open') 
raw_input()

注意! 在python 3中,没有raw_input(),只有 输入()。 (2)使用单引号表示字符串;否则,如果你在任何东西周围输入双精度,比如 "raw_input()",它会认为它是一个函数,变量等,而不是文本。

在下一个例子中,我使用双引号,但它不起作用,因为它认为“the”和“function”之间的引号中有一个断点,尽管当你阅读它时,你自己的大脑可以完全理解它:

print("You have reached the end and the "input()" function is keeping the window open")
input()

希望这能帮助到那些刚开始学习,还不知道计算机是如何思考的人。这可能需要一段时间。: o)

你可以打开PowerShell,输入“python”。 导入Python之后,您可以从您最喜欢的文本编辑器中复制粘贴源代码来运行代码。

窗户关不上。

`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()`
