有时为了对电脑、服务器做运行情况监控，需要获取内存、cpu的使用情况：
# 先下载psutil库:pip install psutil# 下载地址 /project/psutil/5.6.2/import psutildef getMemCpu():data = psutil.virtual_memory()total = data.total # 总内存,单位为byteprint('total',total)free = data.available # 可用内存print('free',free)memory = "Memory usage:%d" % (int(round(data.percent))) + "%" + " " # 内存使用情况print('memory',memory)cpu = "CPU:%0.2f" % psutil.cpu_percent(interval=1) + "%" # CPU占用情况print('cpu',cpu)if __name__ == "__main__":getMemCpu()
