在Python中没有switch语句 If语句 if condition: do sth elif condition: Do sth else: Do sth while语句有一个可选的else从句 while condition: do sth else: do sth for循环 for i in range( 1, 5): # 即序列[1, 2, 3, 4] print i else: print 'The for loop is over' break语句 如果你...
asyncio是 Python 3.4 及以上版本引入的标准库,用于支持异步编程。它通过事件循环(Event Loop)和协程(Coroutine)实现了异步 I/O 操作,使得程序能够在单线程内实现高并发。异步编程的核心思想是在执行 I/O 操作时,不阻塞线程,而是将控制权交回给事件循环,让事件循环可以处理其他任务,当 I/O 操作完成时,再通知事件...

if语句 最常见的流程控制语句是if语句。如果语句的条件是True,那么if语句的子句(即if语句后面的块)将会执行。如果条件为False,则跳过该子句。 简单地说,if语句可以理解为,“如果这个条件为真,则执行子句中的代码”。在 Python 中,if语句由以下内容组成: ...
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模块调用配置模板,以及配合TextFSM、pyATS、Genie等模块将回显内容以有序的JSON格式输出,方便我们过滤和提取出所需的数据等等...
