如何在Python中将彩色文本输出到终端?

如果您使用的是Windows,那么就在这里!

# Display text on a Windows console
# Windows XP with Python 2.7 or Python 3.2
from ctypes import windll

# Needed for Python2/Python3 diff
try:
    input = raw_input
except:
    pass
STD_OUTPUT_HANDLE = -11
stdout_handle = windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
# Look at the output and select the color you want.
# For instance, hex E is yellow on black.
# Hex 1E is yellow on blue.
# Hex 2E is yellow on green and so on.
for color in range(0, 75):
     windll.kernel32.SetConsoleTextAttribute(stdout_handle, color)
     print("%X --> %s" % (color, "Have a fine day!"))
     input("Press Enter to go on ... ")

当我在寻找如何为日志上色时,我被谷歌感动了:

彩色原木

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

注意with关键字与需要重置的修饰符(使用Python 3和Colorama)的混合程度:

from colorama import Fore, Style
import sys

class Highlight:
  def __init__(self, clazz, color):
    self.color = color
    self.clazz = clazz
  def __enter__(self):
    print(self.color, end="")
  def __exit__(self, type, value, traceback):
    if self.clazz == Fore:
      print(Fore.RESET, end="")
    else:
      assert self.clazz == Style
      print(Style.RESET_ALL, end="")
    sys.stdout.flush()

with Highlight(Fore, Fore.GREEN):
  print("this is highlighted")
print("this is not")

try:

如果你正在编程一个游戏,也许你想改变背景颜色,只使用空格?例如:

print " "+ "\033[01;41m" + " " +"\033[01;46m"  + "  " + "\033[01;42m"

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:
