如何在Windows命令行的当前行上覆盖/打印? [英] How can I overwrite/print over the current line in Windows command line?

问题描述

在Unix上，我可以使用\r(回车)或\b(退格键)覆盖shell中的当前行(在已经可见的文本上打印).

On Unix, I can either use \r (carriage return) or \b (backspace) to overwrite the current line (print over text already visible) in the shell.

我可以在Windows命令行中使用Python脚本实现相同的效果吗?

Can I achieve the same effect in a Windows command line from a Python script?

我尝试了curses模块，但Windows上似乎没有该模块.

I tried the curses module but it doesn't seem to be available on Windows.

推荐答案

是:

import sys
import time

def restart_line():
    sys.stdout.write('\r')
    sys.stdout.flush()

sys.stdout.write('some data')
sys.stdout.flush()
time.sleep(2) # wait 2 seconds...
restart_line()
sys.stdout.write('other different data')
sys.stdout.flush()
