如何在Python中将彩色文本输出到终端?
当前回答
您可以使用curses库的Python实现:curses-字符单元显示的终端处理
此外,运行此程序,您将找到您的盒子:
for i in range(255):
print i, chr(i)

class ColorText:
"""
Use ANSI escape sequences to print colors +/- bold/underline to bash terminal.
Examples
--------
>>> ColorText('HelloWorld').bold()
>>> ColorText('HelloWorld').blue()
>>> ColorText('HelloWorld').bold().custom("#bebebe")
>>> ColorText('HelloWorld').underline().custom('dodgerblue')
>>> ColorText.demo()
Notes
-----
- execute ColorText.demo() for a printout of colors.

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:
为了解决这个问题,我创建了一个简单得让人麻木的程序包,用插值颜色代码打印字符串,称为icolor。
icolor包含两个函数:cformat和cprint,每个函数都包含一个字符串和子字符串,这些子字符串被插值以映射到ANSI转义序列。
from icolor import cformat # there is also cprint
cformat("This is #RED;a red string, partially with a #xBLUE;blue background")
'This is \x1b[31ma red string, partially with a \x1b[44mblue background\x1b[0m'
包括所有ANSI颜色(例如#RED;、#BLUE;等)以及#RESET#粗体;以及其他。
背景色具有x前缀,因此绿色背景将为#xGREEN;。
一个人可以用##逃脱#。
鉴于其简单性,最好的文档可能是代码本身。
它在PYPI上,因此可以使用sudo easy_install icolor。
我编写了一个在PyPI上可用的库,它有一个遵循标准打印函数的简单API。
你可以用pip安装着色来安装它。
import coloring
# Directly use print-like functions
coloring.print_red('Hello', 12)
coloring.print_green('Hey', end="", sep=";")
print()
# Get str as return
print(coloring.red('hello'))
# Use the generic colorize function
print(coloring.colorize("I'm red", "red")) # Using color names
print(coloring.colorize("I'm green", (0, 255, 0))) # Using RGB colors
print(coloring.colorize("I'm blue", "#0000ff")) # Using hex colors
# Or using styles (underline, bold, italic, ...)
print(coloring.colorize('Hello', 'red', s='ub')) # underline and bold

我是Python新手,每次我发现像这样的主题时都很兴奋。但这次(突然)我觉得我有话要说。尤其是因为几分钟前,我在Python中发现了一件令人惊叹的事情(至少对我来说是这样):
上下文管理器
from contextlib import contextmanager
# FORECOLOR
BLACKFC,REDFC,GREENFC,YELLOWFC,BLUEFC = '38;30m','38;31m','38;32m','38;33m','38;34m'
# BACKGOUND
BLACKBG,REDBG,GREENBG,YELLOWBG,BLUEBG = '48;40m','48;41m','48;42m','48;43m','48;44m'
@contextmanager
def printESC(prefix, color, text):
print("{prefix}{color}{text}".format(prefix=prefix, color=color, text=text), end='')
yield
print("{prefix}0m".format(prefix=prefix))
with printESC('\x1B[', REDFC, 'Colored Text'):
pass
实例
或者就像这样:
# FORECOLOR
BLACKFC,REDFC,GREENFC,YELLOWFC,BLUEFC = '38;30m','38;31m','38;32m','38;33m','38;34m'
# BACKGOUND
BLACKBG,REDBG,GREENBG,YELLOWBG,BLUEBG = '48;40m','48;41m','48;42m','48;43m','48;44m'
def printESC(prefix, color, text):
print("{prefix}{color}{text}".format(prefix=prefix, color=color, text=text), end='')
print("{prefix}0m".format(prefix=prefix))
printESC('\x1B[', REDFC, 'Colored Text')
