Question

我有一个简单的印刷声明：

print('hello friends')

我希望终端输出为蓝色。我怎样才能用Python3实现这个目标？

Answer 1

这是我用来为Python 3脚本中的特定输出着色的一类。您可以导入该类并使用如下： from colorprint import ColorPrint as _ _.print_fail('Error occurred, quitting program')

import sys

# Colored printing functions for strings that use universal ANSI escape sequences.
# fail: bold red, pass: bold green, warn: bold yellow, 
# info: bold blue, bold: bold white

class ColorPrint:

    @staticmethod
    def print_fail(message, end = '\n'):
        sys.stderr.write('\x1b[1;31m' + message.strip() + '\x1b[0m' + end)

    @staticmethod
    def print_pass(message, end = '\n'):
        sys.stdout.write('\x1b[1;32m' + message.strip() + '\x1b[0m' + end)

    @staticmethod
    def print_warn(message, end = '\n'):
        sys.stderr.write('\x1b[1;33m' + message.strip() + '\x1b[0m' + end)

    @staticmethod
    def print_info(message, end = '\n'):
        sys.stdout.write('\x1b[1;34m' + message.strip() + '\x1b[0m' + end)

    @staticmethod
    def print_bold(message, end = '\n'):
        sys.stdout.write('\x1b[1;37m' + message.strip() + '\x1b[0m' + end)

Answer 2

由于Python是在C语言中解释和运行的，因此无需模块即可设置颜色。

您可以为这样的颜色定义一个类：

class color:
   PURPLE = '\033[1;35;48m'
   CYAN = '\033[1;36;48m'
   BOLD = '\033[1;37;48m'
   BLUE = '\033[1;34;48m'
   GREEN = '\033[1;32;48m'
   YELLOW = '\033[1;33;48m'
   RED = '\033[1;31;48m'
   BLACK = '\033[1;30;48m'
   UNDERLINE = '\033[4;37;48m'
   END = '\033[1;37;0m'

编写代码时，您可以简单地编写：

打印（color.BLUE +“你好朋友” + color.END）

请注意，您选择的颜色必须像您的类定义一样大写，并且这些是我个人认为令人满意的颜色选择。有关颜色选择以及实际上还有背景选择的更多信息，请参见：https://gist.github.com/RabaDabaDoba/145049536f815903c79944599c6f952a。

这是用于C的代码，但是一旦您意识到代码的编写方式，便可以轻松地适应Python。

以蓝色为例，因为这就是您要显示的内容。

BLUE = '033[1;37;48m'

\ 033告诉Python中断并注意以下格式。

1表示代码为粗体。（我更喜欢1到0，因为它会弹出更多。）

34是实际的颜色代码。它选择蓝色。

48m是背景色。 48m与控制台窗口的阴影相同，因此似乎没有背景。

Answer 3

要在控制台中使用颜色，请参阅here和here。

有专门用于此任务的模块，例如colorama和curses

Answer 4

使用colorama非常简单，只需执行此操作：

import colorama
from colorama import Fore, Style
print(Fore.BLUE + "Hello World")

这是Python3 REPL中的运行结果：

并调用此方法重置颜色设置：

print(Style.RESET_ALL)

Answer 5

将这些类放入 test.py 文件附近的 Color.py 文件中，然后运行 test.py 。我已经在Ubuntu Server 16.04和Linux Mint 18.2上测试了这些类。除了GColor（ RGB ）之外，所有类都工作得非常好，它可以在图形终端（如Linux Mint终端）中使用。另外，您可以像下面这样使用这些类：

print(Formatting.Italic + ANSI_Compatible.Color(12) + "This is a " + Formatting.Bold + "test" + Formatting.Reset_Bold +  "!" + ANSI_Compatible.END + Formatting.Reset)
print(Color.B_DarkGray + Color.F_LightBlue + "This is a " + Formatting.Bold + "test" + Formatting.Reset_Bold +  "!" + Base.END)

结果：

注意：它不适用于Windows！

文件 Color.py ：

class Base:
    # Foreground:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    # Formatting
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'    
    # End colored text
    END = '\033[0m'
    NC ='\x1b[0m' # No Color

class ANSI_Compatible:
    END = '\x1b[0m'
    # If Foreground is False that means color effect on Background
    def Color(ColorNo, Foreground=True): # 0 - 255
        FB_G = 38 # Effect on foreground
        if Foreground != True:
            FB_G = 48 # Effect on background
        return '\x1b[' + str(FB_G) + ';5;' + str(ColorNo) + 'm'

class Formatting:
    Bold = "\x1b[1m"
    Dim = "\x1b[2m"
    Italic = "\x1b[3m"
    Underlined = "\x1b[4m"
    Blink = "\x1b[5m"
    Reverse = "\x1b[7m"
    Hidden = "\x1b[8m"
    # Reset part
    Reset = "\x1b[0m"
    Reset_Bold = "\x1b[21m"
    Reset_Dim = "\x1b[22m"
    Reset_Italic = "\x1b[23m"
    Reset_Underlined = "\x1b[24"
    Reset_Blink = "\x1b[25m"
    Reset_Reverse = "\x1b[27m"
    Reset_Hidden = "\x1b[28m"

class GColor: # Gnome supported
    END = "\x1b[0m"
    # If Foreground is False that means color effect on Background
    def RGB(R, G, B, Foreground=True): # R: 0-255  ,  G: 0-255  ,  B: 0-255
        FB_G = 38 # Effect on foreground
        if Foreground != True:
            FB_G = 48 # Effect on background
        return "\x1b[" + str(FB_G) + ";2;" + str(R) + ";" + str(G) + ";" + str(B) + "m"

class Color:
    # Foreground
    F_Default = "\x1b[39m"
    F_Black = "\x1b[30m"
    F_Red = "\x1b[31m"
    F_Green = "\x1b[32m"
    F_Yellow = "\x1b[33m"
    F_Blue = "\x1b[34m"
    F_Magenta = "\x1b[35m"
    F_Cyan = "\x1b[36m"
    F_LightGray = "\x1b[37m"
    F_DarkGray = "\x1b[90m"
    F_LightRed = "\x1b[91m"
    F_LightGreen = "\x1b[92m"
    F_LightYellow = "\x1b[93m"
    F_LightBlue = "\x1b[94m"
    F_LightMagenta = "\x1b[95m"
    F_LightCyan = "\x1b[96m"
    F_White = "\x1b[97m"
    # Background
    B_Default = "\x1b[49m"
    B_Black = "\x1b[40m"
    B_Red = "\x1b[41m"
    B_Green = "\x1b[42m"
    B_Yellow = "\x1b[43m"
    B_Blue = "\x1b[44m"
    B_Magenta = "\x1b[45m"
    B_Cyan = "\x1b[46m"
    B_LightGray = "\x1b[47m"
    B_DarkGray = "\x1b[100m"
    B_LightRed = "\x1b[101m"
    B_LightGreen = "\x1b[102m"
    B_LightYellow = "\x1b[103m"
    B_LightBlue = "\x1b[104m"
    B_LightMagenta = "\x1b[105m"
    B_LightCyan = "\x1b[106m"
    B_White = "\x1b[107m"

然后

文件 test.py ：

from Color import *

if __name__ == '__main__':
    print("Base:")
    print(Base.FAIL,"This is a test!", Base.END)

    print("ANSI_Compatible:")
    print(ANSI_Compatible.Color(120),"This is a test!", ANSI_Compatible.END)

    print("Formatting:")
    print(Formatting.Bold,"This is a test!", Formatting.Reset)

    print("GColor:") # Gnome terminal supported
    print(GColor.RGB(204,100,145),"This is a test!", GColor.END)

    print("Color:")
    print(Color.F_Cyan,"This is a test!",Color.F_Default)

结果：

在Ubuntu Server 16.04上

在Linux Mint 18.2上

Answer 6

我使用colors模块。克隆git存储库，运行setup.py，你很好。然后，您可以非常轻松地打印带有颜色的文本：

import colors
print(colors.red('this is red'))
print(colors.green('this is green'))

这适用于命令行，但可能需要进一步配置IDLE。

Answer 7

这个答案来自早期的python2答案

安装termcolor模块。

pip3 install termcolor
从termcolor导入彩色图书馆。

from termcolor import colored
使用提供的方法，下面是一个例子。

print(colored('hello', 'red'), colored('world', 'green'))

Answer 8

尝试这种方式，无需导入模块，只需使用定义为常量的颜色代码编号：

BLUE = '34m'
message = 'hello friends'


def display_colored_text(color, text):
    colored_text = f"\033[{color}{text}\033[00m"
    return colored_text

示例：

>>> print(display_colored_text(BLUE, message))
hello friends

Answer 9

对于懒惰的人：

无需安装任何其他库，它与我所知道的每个终端都兼容。

分类方法：

首先做import config as cfg。

clipped是数据框。

            #### HEADER: ####
            print('{0:<23} {1:>24} {2:>26} {3:>26} {4:>11} {5:>11}'.format('Road name','Classification','Function','Form of road','Length','Distance') )

            #### Now row by row: ####
            for index, row in clipped.iterrows():
                rdName      = self.colorize(row['name1'],cfg.Green)
                rdClass     = self.colorize(row['roadClassification'],cfg.LightYellow)
                rdFunction  = self.colorize(row['roadFunction'],cfg.Yellow)
                rdForm      = self.colorize(row['formOfWay'],cfg.LightBlue)
                rdLength    = self.colorize(row['length'],cfg.White)
                rdDistance  = self.colorize(row['distance'],cfg.LightCyan)
                print('{0:<30} {1:>35} {2:>35} {3:>35} {4:>20} {5:>20}'.format(rdName,rdClass,rdFunction,rdForm,rdLength,rdDistance) )

{0:<30} {1:>35} {2:>35} {3:>35} {4:>20} {5:>20}的含义：

0, 1, 2, 3, 4, 5->列，在这种情况下总共有6个

30, 35, 20->列的宽度（请注意，您必须添加\033[96m的长度-对于Python来说也是一个字符串），只需进行实验即可：）

>, <->对齐：右，左（也有=用来填充零）

config.py: 中的内容

#colors
ResetAll = "\033[0m"

Bold       = "\033[1m"

ResetBlink      = "\033[25m"
ResetReverse    = "\033[27m"
ResetHidden     = "\033[28m"

Default      = "\033[39m"
Black        = "\033[30m"
Red          = "\033[31m"
