python控制台输出颜色，out()是基本方法，还封装了一些基本颜色方法，如red()，blue()，green()等
out()方法的color参数表示颜色，bgcolor表示背景颜色，style表示样式
其他方法的参数类似，三个参数的具体取值封装到Color类，BGColor类，Style类中。
基本方法：
out(content, color=Color.DEFAULT, bgcolor=BGColor.DEFAULT, style=Style.DEFAULT) red (content [, bgcolor, [style]]) green (content [, bgcolor, [style]]) blue (content [, bgcolor, [style]]) yellow (content [, bgcolor, [style]]) bold (content [, color, [bgcolor]]) underline (content [, color, [bgcolor]]) italic (content [, color, [bgcolor]])
具体代码：
from functools import partial
class Style:
DEFAULT = 0
BOLD= 1
ITALIC = 3
UNDERLINE = 4
ANTIWHITE = 7
class Color:
DEFAULT = 39
BLACK = 30
RED = 31
GREEN = 32
YELLOW = 33
BLUE = 34
PURPLE = 35
CYAN = 36
WHITE = 37
LIGHTBLACK_EX = 90
LIGHTRED_EX = 91
LIGHTGREEN_EX = 92
LIGHTYELLOW_EX = 93
LIGHTBLUE_EX = 94
LIGHTMAGENTA_EX = 95
LIGHTCYAN_EX = 96
LIGHTWHITE_EX = 97
class BGColor:
DEFAULT = 49
BLACK = 40
RED = 41
GREEN = 42
YELLOW = 43
BLUE = 44
PURPLE = 45
CYAN = 46
WHITE = 47
LIGHTBLACK_EX = 100
LIGHTRED_EX = 101
LIGHTGREEN_EX = 102
LIGHTYELLOW_EX = 103
LIGHTBLUE_EX = 104
LIGHTMAGENTA_EX = 105
LIGHTCYAN_EX = 106
LIGHTWHITE_EX = 107
def out(content, color=Color.DEFAULT, bgcolor=BGColor.DEFAULT, style=Style.DEFAULT):
print("\033[{};{};{}m{}\033[0m".format(style, color, bgcolor, content))
red = partial(out, color=Color.RED)
green = partial(out, color=Color.GREEN)
blue = partial(out, color=Color.BLUE)
yellow = partial(out, color=Color.YELLOW)
bold = partial(out, style=Style.BOLD)
underline = partial(out, style=Style.UNDERLINE)
italic = partial(out, style=Style.ITALIC)
红绿灯事件输出颜色示例：
from multiprocessing import Event, Process
import time
import random
from basicPractice import outputscreen # 这里导入了上面写的模块
def car(event: Event, i: int):
if not event.is_set():
outputscreen.out('car{}等待'.format(i),
bgcolor=outputscreen.BGColor.RED)
event.wait()
else:
outputscreen.out('car{}通行'.format(i),
bgcolor=outputscreen.BGColor.GREEN)
def light(event: Event):
while True:
if not event.is_set():
outputscreen.red('红灯亮了', style=outputscreen.Style.BOLD)
time.sleep(1)
event.set()
else:
outputscreen.green('绿灯亮了', style=outputscreen.Style.BOLD)
time.sleep(3)
event.clear()
if __name__ == '__main__':
event = Event()
p = Process(target=light, args=(event,))
p.start()
for i in range(20):
Process(target=car, args=(event, i)).start()
time.sleep(random.random())
