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:
