如何在Python中将彩色文本输出到终端?
当前回答
另一个包装Python3打印功能的PyPI模块:
https://pypi.python.org/pypi/colorprint
如果您也可以从__future_import-print中使用,它可以在Python2.x中使用。下面是模块PyPI页面中的Python 2示例:
from __future__ import print_function
from colorprint import *
print('Hello', 'world', color='blue', end='', sep=', ')
print('!', color='red', format=['bold', 'blink'])
它输出“你好,世界!”,单词为蓝色,感叹号为粗体红色并闪烁。

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
执行代码:
您可以在此处查看所有功能:https://github.com/Nazime/coloring.
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.

@classmethod

您可以使用任何语言提供的shell转义字符。这些转义字符以ESC字符开头,后跟一些参数。
例如,要在终端中输出红色“Hello,World!”字符串:
echo "\e[31m Hello, World! \e[0m"
或者从Python脚本:
print("\e[31m Hello world \e[0m")
此外,我写了一篇关于Escape序列的文章,这可能会帮助您更好地理解这个机制。
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 ... ")
在我看来,这是最简单的方法。只要您具有所需颜色的RGB值,这应该可以工作:
def colored(r, g, b, text):
return f"\033[38;2;{r};{g};{b}m{text}\033[0m"
打印红色文本的示例:
text = 'Hello, World!'
colored_text = colored(255, 0, 0, text)
print(colored_text)
#or
print(colored(255, 0, 0, 'Hello, World!'))
多色文本
text = colored(255, 0, 0, 'Hello, ') + colored(0, 255, 0, 'World')
print(text)
