问题描述

I would like to overwrite something on a line above in a serial console. Is there a character that allows me to move up?

推荐答案

大多数终端都理解 ANSI 转义码.此用例的相关代码:

Most terminals understand ANSI escape codes. The relevant codes for this use case:

• "33[F" – 将光标移动到上一行的开头
• "33[A" – 将光标向上移动一行

• "33[F" – move cursor to the beginning of the previous line
• "33[A" – move cursor up one line

示例(Python):

Example (Python):

print("33[FMy text overwriting the previous line.")
