以前經(jīng)常看到互聯(lián)網(wǎng)大佬的Linux shell腳本啟動的時候顯示一副炫酷的字符畫面，逼格瞬間提升一個檔次，按說字符拼畫也不是什么難事，只要有時間、有耐心(然鵝大部分人這兩樣都沒有)。

網(wǎng)上流傳著一個很老的庫cawsay牛說。cowsay是一個生成ASCII圖片的程序，顯示一頭牛的消息。它也可以使用預(yù)先制作的圖像，以生成其他動物的圖片，如Linux的吉祥物企鵝。由于它是用Perl編寫的，它也適用于其他系統(tǒng)，如微軟的Windows。

cawsay的風(fēng)格看起來是醬嬸兒的

這里要安利的是python的cawsay版本，代碼在這里：
https://github.com/jeffbuttars/cowpy
使用很簡單，一鍵引入python程序，執(zhí)行即可，效果與Linux下的cawsay一樣樣的

安裝

pip install cowpy

使用

#!/usr/bin/env python
# encoding: utf-8

from cowpy import cow

# Create a Cow
cheese = cow.Moose()

# Get a cowsay message by milking the cow
msg = cheese.milk("My witty mesage")

# do something with the message
print(msg)

# Create a Cow with a thought bubble
cheese = cow.Moose(thoughts=True)
msg = cheese.milk("My witty mesage, with thought")
print(msg)

# Create a Cow with a tongue
cheese = cow.Moose(tongue=True)
msg = cheese.milk("My witty mesage, with tongue")
print(msg)

# Create a Cow with dead eyes
cheese = cow.Moose(eyes='dead')
msg = cheese.milk("my witty mesage, i'm dead")
print(msg)

# Get a cow by name
cow_cls = cow.get_cow('moose')
cheese = cow_cls()
msg = cheese.milk("Cow by name is moose")
print(msg)

# Create a Cow with a thought bubble, a tongue, and dead eyes
cheese = cow.Moose(thoughts=True, tongue=True, eyes='dead')
msg = cheese.milk("My witty mesage with several attributes")
print(msg)

這個函數(shù)可以隨機抽一個風(fēng)格的牛生成圖像：

# Create a random cow with a message
msg = cow.milk_random_cow("A random message for fun")
print(msg)

這個方法可以列舉所有備選圖像:

# all the eye options
eye_options = cow.eye_options()
print(eye_options)

# all the cowacter options
cow_options = cow.cow_options()
print(cow_options)

也可以引入fortune的語料庫隨機抽文字給cawsay，如此簡單兩步就可以讓你的python腳本瞬間擁有大佬內(nèi)味兒了。
