如何在Python中将彩色文本输出到终端?


当前回答

试试这个简单的代码

def prRed(prt):
    print(f"\033[91m{prt}\033[00m")

def prGreen(prt):
    print(f"\033[92m{prt}\033[00m")

def prYellow(prt):
    print(f"\033[93m{prt}\033[00m")

def prLightPurple(prt):
    print(f"\033[94m{prt}\033[00m")

def prPurple(prt):
    print(f"\033[95m{prt}\033[00m")

def prCyan(prt):
    print(f"\033[96m{prt}\033[00m")

def prLightGray(prt):
    print(f"\033[97m{prt}\033[00m")

def prBlack(prt):
    print(f"\033[98m{prt}\033[00m")

def prReset(prt):
    print(f"\033[0m{prt}\033[00m")

prGreen("Hello, Green World!")
prBlack("Hello, Black World!")
prCyan("Hello, Cyan World!")
prGreen("Hello, Green World!")
prLightGray("Hello, Light Grey World!")
prLightPurple("Hello, Light Purple World!")
prPurple("Hello, Purple World!")
prRed("Hello, Red World!")
prYellow("Hello, Yellow World!")
prReset("Hello, Reset World!")

Python 3示例

# python2
    def prRed(prt): print("\033[91m {}\033[00m" .format(prt))
    def prGreen(prt): print("\033[92m {}\033[00m" .format(prt))
    def prYellow(prt): print("\033[93m {}\033[00m" .format(prt))
    def prLightPurple(prt): print("\033[94m {}\033[00m" .format(prt))
    def prPurple(prt): print("\033[95m {}\033[00m" .format(prt))
    def prCyan(prt): print("\033[96m {}\033[00m" .format(prt))
    def prLightGray(prt): print("\033[97m {}\033[00m" .format(prt))
    def prBlack(prt): print("\033[98m {}\033[00m" .format(prt))

    prGreen("Hello, World!")

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)

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)

最低等级:

class log:
    f = lambda color: lambda string: print(color + string + "\33[0m")

    black = f("\33[30m")
    red = f("\33[31m")
    green = f("\33[32m")
    yellow = f("\33[33m")
    blue = f("\33[34m")
    magenta = f("\33[35m")
    cyan = f("\33[36m")
    white = f("\33[37m")

# Usage
log.blue("Blue World!")
import click

click.secho('Hello, World!', fg='green')
click.secho('Some more text', bg='blue', fg='white')
click.secho('ATTENTION', blink=True, bold=True)

click(CLI库)有一种非常方便的方式来实现这一点,如果您正在编写命令行工具,无论如何都值得考虑。

这里有一种更有效的方法。

# Colours
pure_red = "\033[0;31m"
dark_green = "\033[0;32m"
orange = "\033[0;33m"
dark_blue = "\033[0;34m"
bright_purple = "\033[0;35m"
dark_cyan = "\033[0;36m"
dull_white = "\033[0;37m"
pure_black = "\033[0;30m"
bright_red = "\033[0;91m"
light_green = "\033[0;92m"
yellow = "\033[0;93m"
bright_blue = "\033[0;94m"
magenta = "\033[0;95m"
light_cyan = "\033[0;96m"
bright_black = "\033[0;90m"
bright_white = "\033[0;97m"
cyan_back = "\033[0;46m"
purple_back = "\033[0;45m"
white_back = "\033[0;47m"
blue_back = "\033[0;44m"
orange_back = "\033[0;43m"
green_back = "\033[0;42m"
pink_back = "\033[0;41m"
grey_back = "\033[0;40m"
grey = '\033[38;4;236m'
bold = "\033[1m"
underline = "\033[4m"
italic = "\033[3m"
darken = "\033[2m"
invisible = '\033[08m'
reverse_colour = '\033[07m'
reset_colour = '\033[0m'
grey = "\x1b[90m"

用户手册

reverseColor表示您反转刚刚选择的颜色,但处于高亮模式(默认为白色)。pink_back(green_back等…带有back的)表示它以粉色突出显示(基于名称)。reset_colour重置颜色(详见图1)。

我相信我不需要解释太多,因为它列在变量名中。
