如何在Python中将彩色文本输出到终端?
当前回答
这里有一个快速类,它包装了一个打印功能,可以快速添加颜色,而无需安装其他软件包。
class PrintColored:
DEFAULT = '\033[0m'

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()
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:
#
如果您正在使用Django:
>>> from django.utils.termcolors import colorize
>>> print colorize("Hello, World!", fg="blue", bg='red',
... opts=('bold', 'blink', 'underscore',))
Hello World!
>>> help(colorize)
快照:
(我通常在runserver终端上使用彩色输出进行调试,所以我添加了它。)
您可以测试它是否安装在您的机器中:$python-c“import django;print django.VERSION”。要安装它,请查看:如何安装django
试试看!!
在Windows上,您可以使用模块“win32console”(在某些Python发行版中可用)或模块“ctypes”(Python 2.5及更高版本)访问Win32 API。
要查看支持这两种方式的完整代码,请参阅Testoob中的彩色控制台报告代码。
ctypes示例:
import ctypes
# Constants from the Windows API
STD_OUTPUT_HANDLE = -11
FOREGROUND_RED = 0x0004 # text color contains red.
def get_csbi_attributes(handle):
# Based on IPython's winconsole.py, written by Alexander Belchenko
import struct
csbi = ctypes.create_string_buffer(22)
res = ctypes.windll.kernel32.GetConsoleScreenBufferInfo(handle, csbi)
assert res
(bufx, bufy, curx, cury, wattr,
left, top, right, bottom, maxx, maxy) = struct.unpack("hhhhHhhhhhh", csbi.raw)
return wattr
handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
reset = get_csbi_attributes(handle)
ctypes.windll.kernel32.SetConsoleTextAttribute(handle, FOREGROUND_RED)
print "Cherry on top"
ctypes.windll.kernel32.SetConsoleTextAttribute(handle, reset)
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)
