如何在Python中将彩色文本输出到终端?
当前回答
定义开始颜色的字符串和结束颜色的字符串。然后打印文本,开始字符串在前面,结束字符串在结尾。
CRED = '\033[91m'
CEND = '\033[0m'
print(CRED + "Error, does not compute!" + CEND)
这将在Bash和urxvt中使用Zenburn风格的配色方案生成以下内容:
通过实验,我们可以获得更多的颜色:
注意:\33[5m和\33[6m闪烁。
这样我们可以创建一个完整的颜色集合:
CEND = '\33[0m'
CBOLD = '\33[1m'
CITALIC = '\33[3m'
CURL = '\33[4m'
CBLINK = '\33[5m'
CBLINK2 = '\33[6m'
CSELECTED = '\33[7m'
CBLACK = '\33[30m'
CRED = '\33[31m'
CGREEN = '\33[32m'
CYELLOW = '\33[33m'
CBLUE = '\33[34m'
CVIOLET = '\33[35m'
CBEIGE = '\33[36m'
CWHITE = '\33[37m'
CBLACKBG = '\33[40m'
CREDBG = '\33[41m'
CGREENBG = '\33[42m'
CYELLOWBG = '\33[43m'
CBLUEBG = '\33[44m'
CVIOLETBG = '\33[45m'
CBEIGEBG = '\33[46m'
CWHITEBG = '\33[47m'
CGREY = '\33[90m'
CRED2 = '\33[91m'
CGREEN2 = '\33[92m'
CYELLOW2 = '\33[93m'
CBLUE2 = '\33[94m'
CVIOLET2 = '\33[95m'
CBEIGE2 = '\33[96m'
CWHITE2 = '\33[97m'
CGREYBG = '\33[100m'
CREDBG2 = '\33[101m'
CGREENBG2 = '\33[102m'
CYELLOWBG2 = '\33[103m'
CBLUEBG2 = '\33[104m'
CVIOLETBG2 = '\33[105m'
CBEIGEBG2 = '\33[106m'
CWHITEBG2 = '\33[107m'
以下是生成测试的代码:
x = 0
for i in range(24):
colors = ""
for j in range(5):
code = str(x+j)
colors = colors + "\33[" + code + "m\\33[" + code + "m\033[0m "
print(colors)
x = x + 5

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)
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()
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)
# Pure Python 3.x demo, 256 colors
# Works with bash under Linux and MacOS
fg = lambda text, color: "\33[38;5;" + str(color) + "m" + text + "\33[0m"
bg = lambda text, color: "\33[48;5;" + str(color) + "m" + text + "\33[0m"
def print_six(row, format, end="\n"):
for col in range(6):
color = row*6 + col - 2
if color>=0:
text = "{:3d}".format(color)
print (format(text,color), end=" ")
else:
print(end=" ") # four spaces
print(end=end)
for row in range(0, 43):
print_six(row, fg, " ")
print_six(row, bg)
# Simple usage: print(fg("text", 160))

def main(stdscr):
stdscr.clear()
if curses.has_colors():
for i in xrange(1, curses.COLORS):
curses.init_pair(i, i, curses.COLOR_BLACK)
stdscr.addstr("COLOR %d! " % i, curses.color_pair(i))
stdscr.addstr("BOLD! ", curses.color_pair(i) | curses.A_BOLD)
stdscr.addstr("STANDOUT! ", curses.color_pair(i) | curses.A_STANDOUT)
stdscr.addstr("UNDERLINE! ", curses.color_pair(i) | curses.A_UNDERLINE)
stdscr.addstr("BLINK! ", curses.color_pair(i) | curses.A_BLINK)
stdscr.addstr("DIM! ", curses.color_pair(i) | curses.A_DIM)
stdscr.addstr("REVERSE! ", curses.color_pair(i) | curses.A_REVERSE)

print "init..."
