如何通过编程将Python整个控制台屏幕的背景颜色更改为特定的RGB颜色?

windows-10 background colors cmd python

user7393973 · 技术社区 · 4 年前

我知道我可以使用颜色命令( documentation link 1 和 documentation link 2 )要从16种可用颜色中选择背景和前景(字体)颜色,请执行以下操作:

import os

os.system('color 8f')

我想知道是否有一个程序化的解决方案,就像对 changing the font color to an RGB value :

import os

os.system('')

def rgb(red, green, blue):
  return f'\x1b[38;2;{red};{green};{blue}m'

red_color = rgb(255, 0, 0)
green_color = rgb(0, 255, 0)
blue_color = rgb(0, 0, 255)

print(f'{red_color}red {green_color}green {blue_color}blue')

我要的是整个控制台屏幕的背景色,而不是背景色 background color of the text . 我也不想安装一些不同的控制台或模块,在不了解如何操作的情况下以某种方式进行安装。

我发现我可以使用 GetConsoleScreenBufferInfoEx 和 SetConsoleScreenBufferInfoEx 函数以编程方式更改控制台16种颜色中任意一种颜色的值。

下面的代码是问答中的代码组合:

Why does the console window shrink when using GetConsoleScreenBufferInfoEx in Windows?

Executable called via subprocess.check_output prints on console but result is not returned

Change entire console background color (Win32 C++)

import ctypes
from ctypes import wintypes
import os
import sys
import time

class COORD(ctypes.Structure):
  _fields_ = (('X', wintypes.SHORT), ('Y', wintypes.SHORT))

class CONSOLE_SCREEN_BUFFER_INFOEX(ctypes.Structure):
  _fields_ = (
    ('cbSize', wintypes.ULONG),
    ('dwSize', COORD),
    ('dwCursorPosition', COORD),
    ('wAttributes', wintypes.WORD),
    ('srWindow', wintypes.SMALL_RECT),
    ('dwMaximumWindowSize', COORD),
    ('wPopupAttributes', wintypes.WORD),
    ('bFullscreenSupported', wintypes.BOOL),
    ('ColorTable', wintypes.DWORD * 16))
  def __init__(self, *args, **kwds):
    super(CONSOLE_SCREEN_BUFFER_INFOEX, self).__init__(*args, **kwds)
    self.cbSize = ctypes.sizeof(self)

def rgb_values_to_integer_color(red, green, blue):
  integer_color = red + (green * 256) + (blue * 256 * 256)
  return integer_color

STD_OUTPUT_HANDLE = -11
console_handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
console_screen_information = CONSOLE_SCREEN_BUFFER_INFOEX()

# get the original color to later set it back
ctypes.windll.kernel32.GetConsoleScreenBufferInfoEx(console_handle, ctypes.byref(console_screen_information))
original_color = console_screen_information.ColorTable[0]

# prevent the console screen's height from shrinking
console_screen_information.srWindow.Bottom += 1

# set the new rgb color
console_screen_information.ColorTable[0] = rgb_values_to_integer_color(red=84, green=170, blue=255)
ctypes.windll.kernel32.SetConsoleScreenBufferInfoEx(console_handle, ctypes.byref(console_screen_information))

# wait 3 seconds
time.sleep(3)

# change back to the original color
console_screen_information.ColorTable[0] = original_color
ctypes.windll.kernel32.SetConsoleScreenBufferInfoEx(console_handle, ctypes.byref(console_screen_information))

第一种颜色(默认为黑色)是正在更改的颜色,因为它是16种颜色中用作背景色的默认颜色。

os.system('cls') (之后 SetConsoleScreenBufferInfoEx ).
