您想了解ANSI转义序列。下面是一个简单的例子：

CSI = "\x1B["
print(CSI+"31;40m" + "Colored Text" + CSI + "0m")

有关详细信息，请参见ANSI转义码。

对于块字符，请尝试使用Unicode字符，如\u2588：

print(u"\u2588")

将所有内容放在一起：

print(CSI+"31;40m" + u"\u2588" + CSI + "0m")

作为RGB标准的粉丝，我会这样做：

def color_text(text, rgb):
    r, g, b = rgb
    return f"\033[38;2;{r};{g};{b}m{text}\033[0m"

class rgb():
    BLACK = (0, 0, 0)
    RED = (255, 0, 0)
    GREEN = (0, 255, 0)
    BLUE = (0, 0, 255)
    YELLOW = (255, 255, 0)
    # and so on ...

print(color_text("hello colored world", rgb.GREEN))

PS：受到CircuitSacul回答的强烈启发

Rich是一个相对较新的Python库，用于在终端中处理颜色。

在Rich中有几种处理颜色的方法。最快的入门方法是富打印方法，它将类似BBCode的语法呈现到ANSI控制代码中：

from rich import print
print("[red]Color[/] in the [bold magenta]Terminal[/]!")

还有其他方法可以通过Rich（正则表达式、语法）和相关的格式化功能应用颜色。
