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?

除了input和raw_input,你还可以使用一个无限while循环,像这样: while True: pass (Python 2.5+/3)或while 1: pass(所有版本的Python 2/3)。不过,这可能需要计算能力。
还可以从命令行运行程序。在命令行中输入python (Mac OS X终端),它应该是python 3。(你的Python版本)如果它没有显示你的Python版本,或者说Python:命令没有找到,查看更改PATH值(环境值,上面列出)/输入C:\(Python文件夹\ Python .exe。如果成功,输入python或C:\(python安装)\python.exe和程序的完整目录。

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。
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()
在windows 10上插入以下语句:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
奇怪,但对我很管用!(当然是和input()一起放在末尾)
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.
