flash钢琴自动弹奏之Python实现

linux系统下没有WSH可用，需要自己实现按键sendkey？python已有实现，virtkey拿来用即可。

不过需要注意的是，按键长度与延时是并行关系。

简单实现：

#!/usr/bin/python

import virtkey
import time
import threading
import sys

speed=0.25

def play(s):
	tid=0
	threading.Thread(target=playb,args=(tid,s)).start()

def playb(tid,s):
	v=virtkey.virtkey()
	ssc=list(s)
	print(ssc)
	for c in ssc:
		v.press_unicode(ord(c))
	time.sleep(speed)
	for c in ssc:
		v.release_unicode(ord(c))


def music(m):
	m=m.strip()
	codes=list(m)
	oncekeys=""
	state=""
	for code in codes:
		if code=="(":
			state="once"
			oncekeys=""
			continue
		if code==")":
			state=""
			play(oncekeys)
			time.sleep(speed)
			continue
		if code=="-":
			time.sleep(speed)
			continue
		if code=="" or code==" " or code=="r" or code=="n":
			continue
		if state=="once":
			oncekeys+=code
			continue
		else:
			play(code)
			time.sleep(speed)
			

time.sleep(3)
if len(sys.argv)==1:
	music("""
