如何在Python中将彩色文本输出到终端?


当前回答

我能找到的最简单的方法不是使用ANSI转义码,而是使用导入模块colorama中的Fore。看看下面的代码:

from colorama import Fore, Style

print(Fore.MAGENTA + "IZZ MAGENTA BRUH.")

print(Style.RESET_ALL + "IZZ BACK TO NORMALZ.")

与ANSI转义码相比:

print("\u001b[31m IZZ RED (NO MAGENTA ON ANSI CODES).\u001b[0m")

print("BACK TO NORMALZ.")

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")

我最终做了这个,我觉得这是最干净的:

formatters = {
    'RED': '\033[91m',
    'GREEN': '\033[92m',
    'END': '\033[0m',
}

print 'Master is currently {RED}red{END}!'.format(**formatters)
print 'Help make master {GREEN}green{END} again!'.format(**formatters)

下面是一个可以这样使用的实现:

from stryle import Stryle

print(Stryle.okgreen.bold@"Hello World" + Stryle.underline@'!' + ' back to normal')
print(f"{Stryle.red}Merry {Stryle.underline.okgreen}Christmas!{Stryle.off}")
print("Merry "@Stryle.red + "Christmas"@Stryle.okgreen.underline)

_decorations = {
    "header" : '\033[95m',
    "okblue" : '\033[94m',
    "okcyan" : '\033[96m',
    "okgreen" : '\033[92m',
    "yellow" : '\033[93m',
    "red" : '\033[91m',
    "warning" : '\033[93m',
    "fail" : '\033[91m',
    "off" : '\033[0m',
    "bold" : '\033[1m',
    "underline" : '\033[4m',
}

class _StringStyle(str):
  def __getattribute__(self, decoration: str = _decorations["off"]):
    if decoration in _decorations:
      return _StringStyle(self.decorations + _decorations[decoration])
    return self
  def __matmul__(self, other):
    return self.decorations + str(other) + _decorations["off"]
  def __rmatmul__(self, other):
    return self.decorations + str(other) + _decorations["off"]
  def __str__(self):
    return self.decorations

Stryle = _StringStyle()

Rich是一个相对较新的Python库,用于在终端中处理颜色。

在Rich中有几种处理颜色的方法。最快的入门方法是富打印方法,它将类似BBCode的语法呈现到ANSI控制代码中:

from rich import print
print("[red]Color[/] in the [bold magenta]Terminal[/]!")

还有其他方法可以通过Rich(正则表达式、语法)和相关的格式化功能应用颜色。

基于joeld的答案,使用https://pypi.python.org/pypi/lazyme 管道安装-U lazyme:

from lazyme.string import color_print
>>> color_print('abc')
abc
>>> color_print('abc', color='pink')
abc
>>> color_print('abc', color='red')
abc
>>> color_print('abc', color='yellow')
abc
>>> color_print('abc', color='green')
abc
>>> color_print('abc', color='blue', underline=True)
abc
>>> color_print('abc', color='blue', underline=True, bold=True)
abc
>>> color_print('abc', color='pink', underline=True, bold=True)
abc

使用新的格式化程序对color_print进行一些更新,例如:

>>> from lazyme.string import palette, highlighter, formatter
>>> from lazyme.string import color_print
>>> palette.keys() # Available colors.
['pink', 'yellow', 'cyan', 'magenta', 'blue', 'gray', 'default', 'black', 'green', 'white', 'red']
>>> highlighter.keys() # Available highlights.
['blue', 'pink', 'gray', 'black', 'yellow', 'cyan', 'green', 'magenta', 'white', 'red']
>>> formatter.keys() # Available formatter,
['hide', 'bold', 'italic', 'default', 'fast_blinking', 'faint', 'strikethrough', 'underline', 'blinking', 'reverse']

注意:斜体、快速闪烁和删除线可能不适用于所有终端,也不适用于Mac和Ubuntu。

例如。,

>>> color_print('foo bar', color='pink', highlight='white')
foo bar
>>> color_print('foo bar', color='pink', highlight='white', reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', bold=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', faint=True, reverse=True)
foo bar
>>> color_print('foo bar', color='pink', highlight='white', underline=True, reverse=True)
foo bar
