[Python]使用ansi color code 让console五颜六色

写了一个Python小程序， 用于输出带ansi color code的字符串，使得在支持vt100的终端上能看见五颜六色的输出。

ESC = chr(27)
# 字体
a_default  = 0
a_bold     = 1
a_italic   = 3
a_underline= 4
# 前景颜色
fg_black   = 30
fg_red     = 31
fg_green   = 32
fg_yellow  = 33
fg_blue    = 34
fg_magenta = 35
fg_cyan    = 36
fg_white   = 37
# 后景颜色
bg_black   = 40
bg_red     = 41
bg_green   = 42
bg_yellow  = 43
bg_blue    = 44
bg_magenta = 45
bg_cyan    = 46
bg_white   = 47

def color_code(a):
    return ESC+"[%dm"%a
    
def color_str(s, *args):
    cs = ""
    for a in args:
        cs += color_code(a)
    cs += s
    cs += color_code(a_default)
    return cs  

用法
比如你可以用

print color_str("hello world", fg_red, bg_black, a_bold)

来生成黑底红字的加粗的hello world
