如何在Python中将彩色文本输出到终端?


当前回答

打印一个开始颜色/样式的字符串,然后是字符串,然后以'\x1b[0m'结束颜色/样式更改:

print('\x1b[6;30;42m' + 'Success!' + '\x1b[0m')

使用以下代码获取shell文本的格式选项表:

def print_format_table():
    """
    prints table of formatted text format options
    """
    for style in range(8):
        for fg in range(30,38):
            s1 = ''
            for bg in range(40,48):
                format = ';'.join([str(style), str(fg), str(bg)])
                s1 += '\x1b[%sm %s \x1b[0m' % (format, format)
            print(s1)
        print('\n')

print_format_table()

其他回答

我已经将joeld的答案打包到一个模块中,该模块具有全局函数,我可以在代码中的任何地方使用这些函数。

文件:log.py

def enable():
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = "\033[1m"

def disable():
    HEADER = ''
    OKBLUE = ''
    OKGREEN = ''
    WARNING = ''
    FAIL = ''
    ENDC = ''

def infog(msg):
    print(OKGREEN + msg + ENDC)

def info(msg):
    print(OKBLUE + msg + ENDC)

def warn(msg):
    print(WARNING + msg + ENDC)

def err(msg):
    print(FAIL + msg + ENDC)

enable()

使用方法如下:

import log
log.info("Hello, World!")
log.err("System Error")

在Windows上,您可以使用模块“win32console”(在某些Python发行版中可用)或模块“ctypes”(Python 2.5及更高版本)访问Win32 API。

要查看支持这两种方式的完整代码,请参阅Testoob中的彩色控制台报告代码。

ctypes示例:

import ctypes

# Constants from the Windows API
STD_OUTPUT_HANDLE = -11
FOREGROUND_RED    = 0x0004 # text color contains red.

def get_csbi_attributes(handle):
    # Based on IPython's winconsole.py, written by Alexander Belchenko
    import struct
    csbi = ctypes.create_string_buffer(22)
    res = ctypes.windll.kernel32.GetConsoleScreenBufferInfo(handle, csbi)
    assert res

    (bufx, bufy, curx, cury, wattr,
    left, top, right, bottom, maxx, maxy) = struct.unpack("hhhhHhhhhhh", csbi.raw)
    return wattr


handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
reset = get_csbi_attributes(handle)

ctypes.windll.kernel32.SetConsoleTextAttribute(handle, FOREGROUND_RED)
print "Cherry on top"
ctypes.windll.kernel32.SetConsoleTextAttribute(handle, reset)
import click

click.secho('Hello, World!', fg='green')
click.secho('Some more text', bg='blue', fg='white')
click.secho('ATTENTION', blink=True, bold=True)

click(CLI库)有一种非常方便的方式来实现这一点,如果您正在编写命令行工具,无论如何都值得考虑。

我有一个叫做colorist的图书馆。这非常简单。

以下是一些示例:

from colorit import *

# Use this to ensure that ColorIt will be usable by certain command line interfaces
# Note: This clears the terminal
init_colorit()

# Foreground
print(color("This text is red", Colors.red))
print(color("This text is orange", Colors.orange))
print(color("This text is yellow", Colors.yellow))
print(color("This text is green", Colors.green))
print(color("This text is blue", Colors.blue))
print(color("This text is purple", Colors.purple))
print(color("This text is white", Colors.white))

# Background
print(background("This text has a background that is red", Colors.red))
print(background("This text has a background that is orange", Colors.orange))
print(background("This text has a background that is yellow", Colors.yellow))
print(background("This text has a background that is green", Colors.green))
print(background("This text has a background that is blue", Colors.blue))
print(background("This text has a background that is purple", Colors.purple))
print(background("This text has a background that is white", Colors.white))

# Custom
print(color("This color has a custom grey text color", (150, 150, 150)))
print(background("This color has a custom grey background", (150, 150, 150)))

# Combination
print(
    background(
        color("This text is blue with a white background", Colors.blue), Colors.white
    )
)

# If you are using Windows Command Line, this is so that it doesn't close immediately
input()

这为您提供了:

值得注意的是,这是跨平台的,已经在Mac、Linux和Windows上进行了测试。

你可能想试试:https://github.com/SuperMaZingCoder/colorit

coloret现在可以与PyPi一起安装了!您可以在Windows上使用pipinstall-color-it安装它,在macOS和Linux上使用pip3 install-color-it安装它。

耶!另一个版本

虽然我觉得这个答案很有用,但我做了一些修改。此GitHub Gist是结果

用法

print colors.draw("i'm yellow", bold=True, fg_yellow=True)

此外,还可以包装常用用法:

print colors.error('sorry, ')
