python - 使用 print() 截断长字符串

Question

我尝试了以下代码

s='Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales'
s1='Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library'
print(s,end='\r')
print(s1)

我得到的输出是

Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library

第一个字符串 s 打印在两行上。 \r 然后从第二行的开头打印第二个字符串。

我希望从第一个字符串的开头打印第二个字符串。是否可以使用 print 来完成此操作，还是应该使用任何其他函数？

Answer 1

这是您正在使用的终端仿真器的一项功能。是的，您可以使用 print 来执行此操作，您需要为您的终端类型输出适当的终端转义序列。

例如，如果您使用的是类似 xterm 的终端仿真器，则转义序列为 described here (该页面适用于 bash，但 python 具有非常相似的语法)。您可能最感兴趣的转义序列是:

• 保存光标位置:\033[s
• 恢复光标位置:\033[u

如果您正在做更复杂的事情，您可能也会对 curses 感兴趣。图书馆。
