python监控键盘输入实例代码

本文研究的主要是python监控键盘输入的相关代码,用到了os,sys,time等,具体实现代码如下:

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import os

import sys

import tty, termios

import time

if __name__ == '__main__':

print "Reading form keybord"

print """ i

j k l

m"""

print 'press Q to quit'

while True:

fd=sys.stdin.fileno()

old_settings=termios.tcgetattr(fd)

#old_settings[3]= old_settings[3] & ~termios.ICANON & ~termios.ECHO

try:

tty.setraw(fd)

ch=sys.stdin.read(1)

finally:

termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)

#print 'error'

if ch=='i':

print 'move forward'

elif ch=='m':

print 'move back'

elif ch=='j':

print "turn left!"

elif ch=='l':

print "turn right!"

elif ch=='u':

print "turn right!"

elif ch=='o':

print "turn right!"

elif ch=='k':

print "stop motor!"

elif ch=='q':

print "shutdown!"

break

elif ord(ch)==0x3:

#这个是ctrl c

print "shutdown"

break

print "Reading form keybord"

print """ i

j k l

m"""

print 'press Q or ctrl+c to quit'

#rate.sleep()

结果:
