python模块——psutil

import psutil

内存

mem = psutil.virtual_memory()
print(mem)
>>> svmem(total=17048064000, available=13197590528, percent=22.6, used=3850473472, free=13197590528)
mem_size = int(mem[0])/1024/1024/1024
print("内存总大小是%.0fG"%mem_size)
>>> 内存总大小是16G
mem_use = int(mem[3])/1024/1024/1024
mem_use_rate = int(mem[3]) / int(mem[0]) *100
print("占用内存%.2fG，占用率%.2f%%"%(mem_use,mem_use_rate))
>>> 占用内存3.59G，占用率22.59%
mem_free = int(mem[4])/1024/1024/1024
print("内存剩余%.2fG"%mem_free)
>>> 内存剩余12.29G　

硬盘

disk1 = psutil.disk_partitions(all)
print("你的磁盘状况如下：")
i = 0
for b in disk1:
b = disk1[i][0]
disk2 = psutil.disk_usage(b)
disk_rate = float(disk2.used / disk2.total *100)
print("%s 总空间%.2f，剩余空间%.2f,使用率%.2f%%"%(b,float(disk2.total/1024/1024/1024),float(disk2.free/1024/1024/1024),float(disk_rate)))
i += 1
>>> 你的磁盘状况如下：
>>> C: 总空间138.89，剩余空间80.40,使用率42.11%
>>> D: 总空间136.80，剩余空间51.44,使用率62.40%
>>> E: 总空间100.00，剩余空间35.72,使用率64.28%
>>> F: 总空间100.00，剩余空间40.66,使用率59.34%

cpu

cpu = psutil.cpu_percent(interval=True)
print(cpu)
cpu1 = psutil.cpu_count()
print(cpu1)
>>> 2.9
>>> 8
