作为Paramiko最为成功的衍生模块,Netmiko成为了很多学习Python网络运维自动化技术的网工日常工作中最常用的模块之一。相较于Paramiko,Netmiko将很多细节优化和简化,比如不需要导入time模块做休眠,输入每条命令不需要在后面加换行符\n,不需要执行config term,exit,end等命令,提取、打印回显内容更方便,可以配合Jinja2模块调用...

字典是一系列由键(key)和值(value)配对组成的元素的集合,在Python3.7+,字典被确定为有序(注意:在3.6中,字典有序是一个implementation detail,在3.7才正式成为语言特性,因此3.6中无法100%确保其有序性),而3.6之前是无序的,其长度大小可变,元素可以任意地删减和改变。 相比于列表和元组,字典的性能更优,特别是对于...
用户按ENTER键退出while循环其实，我想你是在找一个代码，让它在按下键盘的某个键之前一直循环运行。

Chapter 4. Code Reuse: Functions and Modules Reusing code is key to building a maintainable system. And when it comes to reusing code in Python, it all starts and ends … - Selection from Head First Python, 2nd Edition [Book]
exit ( ) time . sleep ( 1 ) The os module in the standard library provides our process ID (PID). psutil constructs a Process() object based on the PID. In this case the PID is our own, but it could be any running process on the system. This looks bad: an infinite loop and an...
