Python 获取计算机信息（操作系统/硬件）

Python中获取计算机的信息，包括操作系统和硬件信息

需要用到的库：platform 和 psutil

1. 获取操作系统信息

import platform

def get_os_info():
    return platform.system(), platform.release()

os_name, os_release = get_os_info()
print(f"操作系统: {os_name} {os_release}")

2. 获取详细的平台信息

def get_platform_info():
    return platform.platform(aliased=True, terse=False)

print(get_platform_info())

3. 获取CPU信息

import platform

def get_cpu_info():
    return platform.processor()

cpu = get_cpu_info()
print(f"处理器: {cpu}")

4. 获取CPU占用率

import psutil

def get_cpu_info_psutil():
    cpu_percent = psutil.cpu_percent(interval=1)
    return cpu_percent

print(f"CPU使用率: {get_cpu_info_psutil()}%")

5. 获取内存信息

import psutil

def get_memory_info():
    mem = psutil.virtual_memory()
    return mem.total, mem.used, mem.percent

total, used, percent = get_memory_info()
print(f"总内存: {total / (1024.0 ** 3):.2f} GB")
print(f"已用内存: {used / (1024.0 ** 3):.2f} GB")
print(f"内存使用率: {percent}%")

6. 获取当前使用的磁盘信息

import psutil

def get_disk_info():
    disk_usage = psutil.disk_usage("/")
    return disk_usage.total, disk_usage.used, disk_usage.free

total, used, free = get_disk_info()
print(f"总磁盘空间: {total / (1024.0 ** 3):.2f} GB")
print(f"已用磁盘空间: {used / (1024.0 ** 3):.2f} GB")
print(f"剩余磁盘空间: {free / (1024.0 ** 3):.2f} GB")

7. 获取所有磁盘驱动的的信息

import psutil

def get_all_disk_info():
    disks = []
    # 获取所有磁盘分区
    for part in psutil.disk_partitions():
        # 使用disk_usage获取每个分区的磁盘使用情况
        usage = psutil.disk_usage(part.mountpoint)
        disks.append({
            'device': part.device,
            'mountpoint': part.mountpoint,
            'fstype': part.fstype,
            'opts': part.opts,
            'total': usage.total,
            'used': usage.used,
            'free': usage.free,
            'percent': usage.percent
        })
    return disks

# 打印所有磁盘信息
for disk_info in get_all_disk_info():
    print(f"设备: {disk_info['device']}")
    print(f"挂载点: {disk_info['mountpoint']}")
    print(f"文件系统类型: {disk_info['fstype']}")
    print(f"挂载选项: {disk_info['opts']}")
    print(f"总大小: {disk_info['total'] / (1024.0 ** 3):.2f} GB")
    print(f"已用空间: {disk_info['used'] / (1024.0 ** 3):.2f} GB")
    print(f"可用空间: {disk_info['free'] / (1024.0 ** 3):.2f} GB")
    print(f"使用率: {disk_info['percent']}%")
    print('---')
