#从1开始，步长为2，即1，3，5，7 ②while循环 while 判断 : 循环体 con�nue #con�nue跳过剩下的循环体，进入下一轮loop，break 跳出整个循环 ★整除 在python 2中，/ 如果参与运算的数为int，就是整除，只取整数 如果 /参与运算的数为float，则返回float，不再是整数 在python schedule_func time {time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())}') time.sleep(1) def loop_monitor(): index = 0 while True: sched1 = sched.scheduler(time.time, time.sleep) strftime("%Y-%m-%d %H:%M:%S", time.localtime())}') index += 1 if __name__ == '__main__': loop_monitor() ★csv模块 在 ★第15章、常用非自带模块 常用的非自带模块，需要使用pip安装 ★paramiko（SSH远程登录） # pip3

familiar with new features in QA, rather than in front of and with the customer – shorter feedback loop  More opportunities to fail, iterate, and improve.  Incented innovation and optimization.  Environment

team responsible for developing the application iii. QA – team responsible for ensuring feedback loop exists to ensure functions as desired iv. Operations – the team responsible for maintaing the production

injection across critical systems ii. Simulate and rehearse accidents for practice 1. Schedule the event 2. Give teams time to prepare, make changes, and establish procedures 3. Execute iii. Expose latent INFORMATION SECURITY INTO PRODUCTION TELEMETRY i. Often production breaches are detected months after the event. A primary reason is due to no one regularly reviewing production logs ii. Use telemetry to help

environments layer a. Events, logs, & metrics b. Common service to centralize, rotate, and delete 2. Event router responsible for storing our events and metrics a. Enables visualization, trending, alerting
