如何打印到彩色控制台？

Question

如何使用python打印以彩色打印。例如

print('This should be red')
print('This should be green')

现在一切都是黑色背景上的白色文字。如果有帮助，我会使用ubuntu。

Answer 1

定义这样的颜色：

W  = '\033[0m'  # white (normal)
R  = '\033[31m' # red
G  = '\033[32m' # green
O  = '\033[33m' # orange
B  = '\033[34m' # blue
P  = '\033[35m' # purple

print(R+"hello how are you"+W)

Answer 2

使用colorconsole之类的模块更容易：

pip install colorconsole

然后，例如

from colorconsole import terminal

screen = terminal.get_terminal(conEmu=False)

screen.cprint(4, 0, "This is red\n")
screen.cprint(10, 0, "This is light green\n")
screen.cprint(0, 11, "This is black on light cyan\n")

screen.reset_colors()

如果可用，它还支持256/24位颜色。

下面是我发现有用的便捷功能。它将以标准RGB元组指定的所需前景色和背景色打印您提供的文本，因此您不必记住ANSI代码。要查找您可能要使用的RGB值，可以使用https://www.w3schools.com/colors/colors_picker.asp上的颜色选择器。

def print_in_color(txt_msg,fore_tupple,back_tupple,):
    #prints the text_msg in the foreground color specified by fore_tupple with the background specified by back_tupple 
    #text_msg is the text, fore_tupple is foregroud color tupple (r,g,b), back_tupple is background tupple (r,g,b)
    rf,gf,bf=fore_tupple
    rb,gb,bb=back_tupple
    msg='{0}' + txt_msg
    mat='\33[38;2;' + str(rf) +';' + str(gf) + ';' + str(bf) + ';48;2;' + str(rb) + ';' +str(gb) + ';' + str(bb) +'m' 
    print(msg .format(mat))
    print('\33[0m') # returns default print color to back to black

# example of use using a message with variables
fore_color='cyan'
back_color='dark green'
msg='foreground color is {0} and the background color is {1}'.format(fore_color, back_color)
print_in_color(msg, (0,255,255),(0,127,127))

Answer 4

使用彩色模块。

import colored
color = colored.fg(196) #orange
print(color + "This text is orange")

在此使用此功能：它具有颜色：红色，蓝色，绿色

colors = {'red':'\033[31m', 'blue':'\033[34m', 'green':'\033[32m'}

def colorprint(string, text_color = 'default', bold = False, underline = False):
    if underline == True:
            string = '\033[4m' + string
    if bold == True:
            string = '\033[1m' + string
    if text_color == 'default' or text_color in colors:
            for color in colors:
                    if text_color == color:
                            string = colors[color] + string
    else:
            raise ValueError ("Colors not in:", colors.keys())

    print(string + '\033[0m')
