如何在Python中将彩色文本输出到终端?
当前回答
sty类似于colorama,但它不那么冗长,支持8位和24位(RGB)颜色,支持所有效果(粗体、下划线等),允许您注册自己的样式,是完全类型和高性能的,支持静音,不干扰全局设置,如sys.stdout,真的很灵活,文档很好,等等。。。
示例:
from sty import fg, bg, ef, rs
foo = fg.red + 'This is red text!' + fg.rs
bar = bg.blue + 'This has a blue background!' + bg.rs
baz = ef.italic + 'This is italic text' + rs.italic
qux = fg(201) + 'This is pink text using 8bit colors' + fg.rs
qui = fg(255, 10, 10) + 'This is red text using 24bit colors.' + fg.rs
# Add custom colors:
from sty import Style, RgbFg
fg.orange = Style(RgbFg(255, 150, 50))
buf = fg.orange + 'Yay, Im orange.' + fg.rs
print(foo, bar, baz, qux, qui, buf, sep='\n')

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")
我已经将joeld的答案打包到一个模块中,该模块具有全局函数,我可以在代码中的任何地方使用这些函数。
文件:log.py
def enable():
HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
BOLD = "\033[1m"
def disable():
HEADER = ''
OKBLUE = ''
OKGREEN = ''
WARNING = ''
FAIL = ''
ENDC = ''
def infog(msg):
print(OKGREEN + msg + ENDC)
def info(msg):
print(OKBLUE + msg + ENDC)
def warn(msg):
print(WARNING + msg + ENDC)
def err(msg):
print(FAIL + msg + ENDC)
enable()
使用方法如下:
import log
log.info("Hello, World!")
log.err("System Error")
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)
def black(text):
print('\033[30m', text, '\033[0m', sep='')
def red(text):
print('\033[31m', text, '\033[0m', sep='')
def green(text):
print('\033[32m', text, '\033[0m', sep='')
def yellow(text):
print('\033[33m', text, '\033[0m', sep='')
def blue(text):
print('\033[34m', text, '\033[0m', sep='')
def magenta(text):
print('\033[35m', text, '\033[0m', sep='')
def cyan(text):
print('\033[36m', text, '\033[0m', sep='')
def gray(text):
print('\033[90m', text, '\033[0m', sep='')
black("BLACK")
red("RED")
green("GREEN")
yellow("YELLOW")
blue("BLACK")
magenta("MAGENTA")
cyan("CYAN")
gray("GRAY")

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")
