1. 文本操作

2. 系统信息监控~psutil 模块

psutil 模块官方文档：https://psutil.readthedocs.io/en/latest/#

psutil（python 系统和进程实用程序）是一个跨平台库，用于 在Python中检索有关正在运行的进程和系统利用率（CPU、内存、磁盘、网络、传感器）的信息。
它主要用于系统监控、分析、限制进程资源和管理正在运行的进程。它实现了 UNIX 命令行工具提供的许多功能，例如：ps、top、lsof、netstat、ifconfig、who、
df、kill、free、nice、ionice、iostat、iotop、uptime、pidof、tty、taskset、pmap。psutil 目前支持以下平台：
    Linux
    视窗
    苹果系统
    FreeBSD、OpenBSD、NetBSD
    太阳索拉里斯
    艾克斯

1. 获取/监控cpu 信息

>>> import psutil
#获取CPU逻辑数量
>>> psutil.cpu_count()
16
#获取CPU物理数量
>>> psutil.cpu_count(logical=False)
8
#获取CPU占比
>>> psutil.cpu_percent()
1.7
#获取每个CPU占比
>>> psutil.cpu_percent(percpu=True)
[5.5, 0.8, 4.5, 1.3, 2.9, 0.3, 1.2, 0.4, 0.9, 0.1, 4.1, 0.2, 3.9, 0.2, 1.6, 1.0]

2. 获取/监控内存信息

>>> import psutil
>>> psutil.virtual_memory()
svmem(total=16540291072, available=5063139328, percent=69.4, used=11477151744, free=5063139328)

3. 监控磁盘信息

>>> psutil.disk_partitions()
[sdiskpart(device='C:\\', mountpoint='C:\\', fstype='NTFS', opts='rw,fixed', maxfile=255, maxpath=260), sdiskpart(device='D:\\', mountpoint='D:\\', fstype='NTFS', opts='rw,fixed', maxfile=255, maxpath=260), sdiskpart(device='E:\\', mountpoint='E:\\', fstype='NTFS', opts='rw,fixed', maxfile=255, maxpath=260), sdiskpart(device='F:\\', mountpoint='F:\\', fstype='NTFS', opts='rw,fixed', maxfile=255, maxpath=260), sdiskpart(device='G:\\', mountpoint='G:\\', fstype='NTFS', opts='rw,fixed', maxfile=255, maxpath=260)]

>>> psutil.disk_usage('/')
sdiskusage(total=128849014784, used=77110710272, free=51738304512, percent=59.8)
>>> psutil.disk_io_counters()
