是否可以使用非 ANSI 颜色从 Python 打印？
Is it possible to print from Python using non-ANSI colors?
我正在尝试使用 Python 以自定义颜色将文本打印到终端 log/print。我环顾四周，但除了 ANSI colors.
之外找不到任何东西
我是否必须使用 ANSI 颜色，或者我是否可以 log/print 使用自定义颜色（例如，使用 RGB 或十六进制值）的文本到终端？

好吧，这是一个用于 256 色 xterm 调色板的 Python 3。来自 here. (I can't remember why I called it "aixterm" - as Thomas Dickey pointed out in a comment, this is actually for xterm.) The xterm FAQ on colors 的 Escape-code/hex 值映射也可能有帮助。
import myaixterm，调用 aix_init()，然后调用 print(aix_fg(128),'whatever',aix_normal())。
根据 this.，Edit 现在具有 aix_fg_rgb 和 aix_bg_rgb 功能

正如我在评论中所说，"Python has nothing to do with the colors you are able to use or not. Your terminal does. What happens is that the ANSI extensions with printable sequence codes that allow selecting a broader color range in the terminal are buried within the Internet."
正好在Wikipedia article for ANSI escape codes上可以找到关于24位终端颜色扩展的信息。
因为它们需要一些工作才能使用，所以我创建了一个实用函数，可以在终端上打印任意颜色和渐变：
https://gist.github.com/jsbueno/6577d5514f43f128af826148605f2a2a
如果更多人感兴趣，也许可以将其升级为完整的 Python 包。
我正在尝试使用 Python 以自定义颜色将文本打印到终端 log/print。我环顾四周，但除了 ANSI colors.
之外找不到任何东西我是否必须使用 ANSI 颜色，或者我是否可以 log/print 使用自定义颜色（例如，使用 RGB 或十六进制值）的文本到终端？

正如我在评论中所说，"Python has nothing to do with the colors you are able to use or not. Your terminal does. What happens is that the ANSI extensions with printable sequence codes that allow selecting a broader color range in the terminal are buried within the Internet."
正好在Wikipedia article for ANSI escape codes上可以找到关于24位终端颜色扩展的信息。 因为它们需要一些工作才能使用，所以我创建了一个实用函数，可以在终端上打印任意颜色和渐变：

如果更多人感兴趣，也许可以将其升级为完整的 Python 包。
