如何在获得输出后立即阻止 python.exe 关闭? [英] How can I stop python.exe from closing immediately after I get an output?

问题描述

有什么办法可以阻止 python.exe 在完成后立即关闭?它关闭的速度比我读取输出的速度要快.

Is there any way I can stop python.exe from closing immediately after it completes? It closes faster than I can read the output.

这是程序:

width = float(input("Enter the width: "))
height = float(input("Enter the height: "))
area = width * height
print("The area is", area, "square units.")

推荐答案

你不能 - 全局，即对于每个 python 程序.这是一件好事 - Python 非常适合编写脚本(自动化内容)，并且脚本应该能够在没有任何用户交互的情况下运行.

You can't - globally, i.e. for every python program. And this is a good thing - Python is great for scripting (automating stuff), and scripts should be able to run without any user interaction at all.

但是，您始终可以在程序结束时要求输入，从而有效地使程序保持活动状态，直到您按下回车键.在 Python 3 中使用 input("prompt: ")(或 Python 2 中的 raw_input("promt: ")).或者习惯于从命令行运行程序(即 python mine.py)，程序将退出，但其输出仍然可见.

However, you can always ask for input at the end of your program, effectively keeping the program alive until you press return. Use input("prompt: ") in Python 3 (or raw_input("promt: ") in Python 2). Or get used to running your programs from the command line (i.e. python mine.py), the program will exit but its output remains visible.
