如何在Python中将彩色文本输出到终端?
当前回答
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))

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.

对于字符
您的终端很可能使用Unicode(通常为UTF-8编码)字符,所以只需选择合适的字体即可看到您喜爱的字符。Unicode字符U+2588,“完整块”是我建议您使用的字符。
尝试以下操作:
import unicodedata
fp= open("character_list", "w")
for index in xrange(65536):
char= unichr(index)
try: its_name= unicodedata.name(char)
except ValueError: its_name= "N/A"
fp.write("%05d %04x %s %s\n" % (index, index, char.encode("UTF-8"), its_name)
fp.close()
稍后使用您喜爱的查看器检查文件。
对于颜色
curses是您要使用的模块。查看本教程。
您想了解ANSI转义序列。下面是一个简单的例子:
CSI = "\x1B["
print(CSI+"31;40m" + "Colored Text" + CSI + "0m")
有关详细信息,请参见ANSI转义码。
对于块字符,请尝试使用Unicode字符,如\u2588:
print(u"\u2588")
将所有内容放在一起:
print(CSI+"31;40m" + u"\u2588" + CSI + "0m")
我有一个叫做colorist的图书馆。这非常简单。
以下是一些示例:
from colorit import *
# Use this to ensure that ColorIt will be usable by certain command line interfaces
# Note: This clears the terminal
init_colorit()
# Foreground
print(color("This text is red", Colors.red))
print(color("This text is orange", Colors.orange))
print(color("This text is yellow", Colors.yellow))
print(color("This text is green", Colors.green))
print(color("This text is blue", Colors.blue))
print(color("This text is purple", Colors.purple))
print(color("This text is white", Colors.white))
# Background
print(background("This text has a background that is red", Colors.red))
print(background("This text has a background that is orange", Colors.orange))
print(background("This text has a background that is yellow", Colors.yellow))
print(background("This text has a background that is green", Colors.green))
print(background("This text has a background that is blue", Colors.blue))
print(background("This text has a background that is purple", Colors.purple))
print(background("This text has a background that is white", Colors.white))
# Custom
print(color("This color has a custom grey text color", (150, 150, 150)))
print(background("This color has a custom grey background", (150, 150, 150)))
# Combination
print(
background(
color("This text is blue with a white background", Colors.blue), Colors.white
)
)
# If you are using Windows Command Line, this is so that it doesn't close immediately
input()

值得注意的是,这是跨平台的,已经在Mac、Linux和Windows上进行了测试。

coloret现在可以与PyPi一起安装了!您可以在Windows上使用pipinstall-color-it安装它,在macOS和Linux上使用pip3 install-color-it安装它。
