篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了python pynput鼠标键盘监控（详细）第2部键盘监控tcy相关的知识，希望对你有一定的参考价值。


1.类键盘监听实现
 
"""1.作者：tcy 写于上海叶榭。2018/8/30
   2.用途：实时监听键盘，可用来启停程序，键盘中断。
           如输入stop停止事件，输入start开始运行。
   3.平台：window7 python3.7 PyCharm模拟。
   4.技术说明：用程序和类分别包装。建议用类
               监听部分有暂停键盘监听，恢复监听，销毁监听；
               暂停后可以恢复，但销毁后不能再恢复"""
