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?

用下面两行代码创建一个Windows批处理文件:
python your-program.py
pause

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.
你可以使用-i选项启动python,或者设置环境变量PYTHONINSPECT=x。从文档中可以看出:
运行脚本后进行交互检查;强制执行提示符甚至 如果stdin看起来不是终结符;还PYTHONINSPECT = x
所以当你的脚本崩溃或完成时,你会得到一个python提示符,你的窗口不会关闭。
让窗户一直开着的简单方法:
counter = 0
While (True):
If (counter == 0):
# Code goes here
counter += 1
计数器是这样代码就不会重复自己。
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。
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;")
