从Python [Eclipse]清除命令行输出 [英] Clear command line output from Python [Eclipse]

问题描述

我正在使用Eclipse编写Python，我想要能够轻松地清除屏幕。我已经看到这个问题，并尝试（其中建议）以下解决方案

I'm using Eclipse for writing Python, and I want to be able to easily clear the screen. I've seen this question, and tried (among other things suggested there) the following solution

import os

def clear():
    os.system('cls' if os.name == 'nt' else 'clear')

但它没有'完全解决我的问题。而不是清除屏幕，例程会在Eclipse中的命令输出窗口中打印一个小的正方形（好像想打印一个未知的字符）。

but it doesn't entirely solve my problem. Instead of clearing the screen, the routine prints a small square (as if wanting to print an unknown character) to the command output window in Eclipse.

键入 cls 在命令行中工作得很好，运行Python脚本与上述代码从命令行运行。但是如何在Eclipse中看起来不错？

Typing cls in the command line works perfectly fine, as does running a Python script with the above code from command line. But how can I make it look nice in Eclipse as well?

推荐答案

在eclipse中运行它的问题是 cls 使用ANSI转义序列来清除屏幕。我的意思是要清除屏幕， cls 写入一个字符串，如\033 [[80; j到输出缓冲区。本机控制台（eclipse之外的）将此解释为一个清除屏幕的命令，但是eclipse控制台不了解它，所以只需打印一个小的正方形，就像打印一个未知字符一样。

The problem with running it in eclipse is that cls uses ANSI escape sequences to clear the screen. What I mean by this is that to clear the screen, cls writes a string such as "\033[[80;j" to the output buffer. The native console (the one outside of eclipse) interprets this as a command to clear the screen, but the eclipse console doesn't understand it, so just prints a small square as if printing an unknown character.
