如何在Python中将彩色文本输出到终端?


当前回答

这里有一种更有效的方法。

# Colours
pure_red = "\033[0;31m"
dark_green = "\033[0;32m"
orange = "\033[0;33m"
dark_blue = "\033[0;34m"
bright_purple = "\033[0;35m"
dark_cyan = "\033[0;36m"
dull_white = "\033[0;37m"
pure_black = "\033[0;30m"
bright_red = "\033[0;91m"
light_green = "\033[0;92m"
yellow = "\033[0;93m"
bright_blue = "\033[0;94m"
magenta = "\033[0;95m"
light_cyan = "\033[0;96m"
bright_black = "\033[0;90m"
bright_white = "\033[0;97m"
cyan_back = "\033[0;46m"
purple_back = "\033[0;45m"
white_back = "\033[0;47m"
blue_back = "\033[0;44m"
orange_back = "\033[0;43m"
green_back = "\033[0;42m"
pink_back = "\033[0;41m"
grey_back = "\033[0;40m"
grey = '\033[38;4;236m'
bold = "\033[1m"
underline = "\033[4m"
italic = "\033[3m"
darken = "\033[2m"
invisible = '\033[08m'
reverse_colour = '\033[07m'
reset_colour = '\033[0m'
grey = "\x1b[90m"

用户手册

reverseColor表示您反转刚刚选择的颜色,但处于高亮模式(默认为白色)。pink_back(green_back等…带有back的)表示它以粉色突出显示(基于名称)。reset_colour重置颜色(详见图1)。

我相信我不需要解释太多,因为它列在变量名中。

如果您想尝试代码,请转到replit IDE测试代码。示例代码在这里

当我在寻找如何为日志上色时,我被谷歌感动了:

安装

pip install coloredlogs

用法

最小使用量:

import logging
import coloredlogs

coloredlogs.install()  # install a handler on the root logger

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果如下:

从消息级调试开始:

import logging
import coloredlogs

coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果如下:

隐藏库中的邮件:

import logging
import coloredlogs

logger = logging.getLogger(__name__)  # get a specific logger object
coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger)  # pass a specific logger object

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果如下:

设置日志消息格式:

import logging
import coloredlogs

logger = logging.getLogger(__name__)  # get a specific logger object
coloredlogs.install(level='DEBUG')  # install a handler on the root logger with level debug
coloredlogs.install(level='DEBUG', logger=logger)  # pass a specific logger object
coloredlogs.install(
    level='DEBUG', logger=logger,
    fmt='%(asctime)s.%(msecs)03d %(filename)s:%(lineno)d %(levelname)s %(message)s'
)

logging.debug('message with level debug')
logging.info('message with level info')
logging.warning('message with level warning')
logging.error('message with level error')
logging.critical('message with level critical')

结果如下:

可用的格式属性:

%(asctime)s-发出日志记录调用时,作为人类可读字符串的时间%(created)f-发出日志调用时的浮点时间%(filename)s-文件名%(funcName)s-包含日志记录调用的函数的名称%(hostname)s-系统主机名%(levelname)s-文本日志记录级别%(levelno)s-整数日志记录级别%(lineno)d-发出记录调用的行号%(message)s-传递给日志记录调用的消息(与%(msg)s相同)%(module)s—发出日志记录调用的不带扩展名的文件名%(毫秒)d-发出日志调用的毫秒部分%(msg)s-传递给日志记录调用的消息(与%(Message)s相同)%(name)s-记录器名称%(pathname)s—包含日志记录调用的文件的完整路径名%(process)d-进程ID%(processName)s-进程名称%(programname)s-系统程序名%(relativeCreated)d-发出日志调用时的时间(以毫秒为单位),相对于加载日志模块的时间%(thread)d-线程ID%(threadName)s-线程名称%(username)s-系统用户名

日志记录库

对于Windows,除非使用Win32 API,否则无法使用颜色打印到控制台。

对于Linux,它就像使用打印一样简单,转义序列如下:

颜色

要使字符像方框一样打印,这实际上取决于控制台窗口使用的字体。磅符号效果很好,但它取决于字体:

#
print("\033[1;32;40m Bright Green  \n")

答案是Python中所有跨平台着色的Colorama。

它支持Python 3.5+以及Python 2.7。

截至2021 1月,这一数字仍保持不变。

示例代码:

from colorama import init as colorama_init
from colorama import Fore
from colorama import Style

colorama_init()

print(f"This is {Fore.GREEN}color{Style.RESET_ALL}!")

屏幕截图示例:

作为RGB标准的粉丝,我会这样做:

def color_text(text, rgb):
    r, g, b = rgb
    return f"\033[38;2;{r};{g};{b}m{text}\033[0m"

class rgb():
    BLACK = (0, 0, 0)
    RED = (255, 0, 0)
    GREEN = (0, 255, 0)
    BLUE = (0, 0, 255)
    YELLOW = (255, 255, 0)
    # and so on ...

print(color_text("hello colored world", rgb.GREEN))
