如何在Python中将彩色文本输出到终端?


当前回答

class ColorText:
    """
    Use ANSI escape sequences to print colors +/- bold/underline to bash terminal.

    Examples
    --------
    >>> ColorText('HelloWorld').bold()
    >>> ColorText('HelloWorld').blue()
    >>> ColorText('HelloWorld').bold().custom("#bebebe")
    >>> ColorText('HelloWorld').underline().custom('dodgerblue')
    >>> ColorText.demo()

    Notes
    -----
    - execute ColorText.demo() for a printout of colors.

试试这个简单的代码

    print(f"\033[91m{prt}\033[00m")

def prGreen(prt):
    print(f"\033[92m{prt}\033[00m")

def prYellow(prt):
    print(f"\033[93m{prt}\033[00m")

如果你正在编程一个游戏,也许你想改变背景颜色,只使用空格?例如:

print " "+ "\033[01;41m" + " " +"\033[01;46m"  + "  " + "\033[01;42m"

我建议这个新图书馆Printy。他们刚刚发布了版本1.2.0作为跨平台库。

过来看:GitHub上的Printy

它基于标志,所以你可以做类似的事情

from printy import printy

# With global flags, this will apply a bold (B) red (r) color and an underline (U) to the whole text
printy("Hello, World!", "rBU")

# With inline formats, this will apply a dim (D)
#blue (b) to the word 'Hello' and a stroken (S)
#yellow (y) to the word 'world', and the rest will remain as the predefined format
printy("this is a [bD]Hello@ [yS]world@ text")

这里有一个快速类,它包装了一个打印功能,可以快速添加颜色,而无需安装其他软件包。

输出

这在某种程度上取决于您所在的平台。最常见的方法是打印ANSI转义序列。举个简单的例子,这里有一些来自Blender构建脚本的Python代码:

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKCYAN = '\033[96m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

要使用这样的代码,可以执行以下操作:

print(bcolors.WARNING + "Warning: No active frommets remain. Continue?" + bcolors.ENDC)

或者,使用Python 3.6+:

print(f"{bcolors.WARNING}Warning: No active frommets remain. Continue?{bcolors.ENDC}")

这将在包括OS X、Linux和Windows在内的UNIX上运行(如果您使用ANSICON,或者在Windows 10中启用VT100仿真)。有用于设置颜色、移动光标等的ANSI代码。

如果你要对此感到复杂(如果你正在编写游戏,这听起来就像是这样),你应该看看“诅咒”模块,它为你处理了很多复杂的部分。Python诅咒HowTO是一个很好的介绍。

如果您不使用扩展ASCII(即,不在PC上),则您只能使用127以下的ASCII字符,而“#”或“@”可能是块的最佳选择。如果您可以确保您的终端使用的是IBM扩展的ASCII字符集,那么您有更多的选项。字符176、177、178和219是“块字符”。

一些基于文本的现代程序,如“矮人堡垒”,以图形模式模拟文本模式,并使用经典PC字体的图像。您可以在矮人要塞Wiki中找到一些位图(用户制作的瓷砖)。

文本模式演示比赛有更多的资源用于在文本模式下制作图形。
