Python中psutil的介绍与用法

import psutil

disk = psutil.disk_partitions()
for i in disk:
 print("磁盘：%s 分区格式:%s" % (i.device, i.fstype)) # 盘符 分区格式
 disk_use = psutil.disk_usage(i.device) 

 print("使用了：%.1f GB,空闲：%.1f GB,总共：%.1f GB,使用率%.1f%%," % (
 disk_use.used / 1024 / 1024 / 1024, disk_use.free / 1024 / 1024 / 1024, disk_use.total / 1024 / 1024 / 1024,
 disk_use.percent))

memory = psutil.virtual_memory()
# memory.used 使用的
# memory.total 总共
ab = float(memory.used) / float(memory.total) * 100
print("内存使用率为:%.2f%%" % ab)

print(psutil.net_io_counters(pernic=True))
