Python的Colorama模块,能够跨多终端,显示字体不一样的颜色和背景,只须要导入colorama模块便可,不用再每次都像linux同样指定颜色。python
pip install colorama
Fore是针对字体颜色,Back是针对字体背景颜色,Style是针对字体格式linux
Fore: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. Back: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. Style: DIM, NORMAL, BRIGHT, RESET_ALL
注意,颜色RED,GREEN都须要大写,先指定是颜色和样式是针对字体仍是字体背景,而后再添加颜色,颜色就是英文单词指定的颜色 git
from colorama import Fore, Back, Style print(Fore.RED + 'some red text') print(Back.GREEN + 'and with a green background') print(Style.DIM + 'and in dim text') print(Style.RESET_ALL) print('back to normal now')
输出结果windows
# 记得要及时关闭colorma的做用范围
# 若是不关闭的话,后面全部的输出都会是你指定的颜色
print(Style.RESET_ALL)
init()接受一些* * kwargs覆盖缺省行为,dom
autoreset是自动恢复到默认颜色字体
init(autoreset = False):
init(wrap=True):The default behaviour is to convert if on Windows and output is to a tty (terminal). spa
在windows系统终端输出颜色要使用init(wrap=True)3d
#!/usr/bin/env python #encoding: utf-8 from colorama import init, Fore, Back, Style if __name__ == "__main__": init(autoreset=True) # 初始化,而且设置颜色设置自动恢复 print(Fore.RED + 'some red text') print(Back.GREEN + 'and with a green background') print(Style.DIM + 'and in dim text') # 若是未设置autoreset=True,须要使用以下代码重置终端颜色为初始设置 #print(Fore.RESET + Back.RESET + Style.RESET_ALL) autoreset=True print('back to normal now')
输出结果orm
