在实际运行Python脚本的过程中控制台有时满屏清一色的白色输出很不易于识别，如下图。
因此需要给控制台的输出增加点色彩。总的说来利用Python实现彩色输出还是比较简单的。 经过测试，在Windows系统控制台(CMD)中，需要通过Python调用系统的API来实现。 在Python的控制台中，遵循Python的语法规则即可实现。 在Linux下，直接使用Python语法即可。 而至于在MacOS下，由于没有苹果系统所以没有测试了。 但估计应该也是符合Python语法即可，只有Windows比较特殊一点。 这里简单记录一下用法。
1.代码
由于代码比较简单，下面直接贴代码。

import os
import sys
import platform

STD_OUTPUT_HANDLE = -11
STD_ERROR_HANDLE = -12
# 字体颜色定义 ,关键在于颜色编码，由2位十六进制组成，分别取0~f，前一位指的是背景色，后一位指的是字体色
# 由于该函数的限制，应该是只有这16种，可以前景色与背景色组合。也可以几种颜色通过或运算组合，组合后还是在这16种颜色中
# Windows CMD命令行 字体颜色定义 text colors
FOREGROUND_BLACK = 0x00 # black.
FOREGROUND_DARKBLUE = 0x01 # dark blue.

以后在Windows上使用时，可以直接拷贝定义的这些变量和函数，然后调用即可。 对于Linux，符合Python规定语法即可。
2.测试
首先是在Windows系统控制台中。
可以看到Python语法是失效的，对系统控制台无效。然后是在Python控制台中。
在这里Windows API失效了，但Python语法有效。最后在Linux上测试，如下。
