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?

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.

创建一个像dontClose()这样的函数或带有while循环的函数:

import time

def dontClose():
    n = 1
    while n > 0:
        n += 1
        time.sleep(n)
        

然后在代码之后运行函数。例如:

print("Hello, World!")
dontClose()

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。

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。

你可以组合答案之前:(notepad++用户)

按F5运行当前脚本并输入命令:

cmd /k python -i "$(FULL_CURRENT_PATH)"

这样,在执行notepad++ python脚本后,您将保持在交互模式,并且您能够使用您的变量等等:)

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)
