前言
最近在项目中需要输出彩色的文字来提醒用户,以前写过,但是只能在win上面运行。
今天搜了下看有没有在win和Linux上通用的输出彩色文字的模块,结果发现没有,,于是就自己弄了一个,分享下,以后用的时候翻翻博客,方便别人也方便自己。
win下输出彩色文字,网上有两种方法一种是用system执行命令来设置颜色,感觉还是不太好,用ctypes模块实现更好点。
linux下设置颜色,网上只找到了一种方法,下面不废话了,直接贴下代码:

用起来很容易,直接from color import *
就可以用了,有4种常用颜色可以使用,分别写了4个函数:
提示信息 printBlue
成功信息 printGreen
失败信息 printRed
警告信息 printYellow
和bootstrap的几种颜色差不多,应该够用了。
