做某项目时，需要获取文件夹大小，磁盘的存储信息。通过学习整理了下，仅供参考。

获取某个目录的大小

def get_size(path):list1 = []fileList = os.listdir(path)  # 获取path目录下所有文件for filename in fileList:pathTmp = os.path.join(path,filename)  # 获取path与filename组合后的路径if os.path.isdir(pathTmp):   # 判断是否为目录get_size(pathTmp)        # 是目录就继续递归查找elif os.path.isfile(pathTmp):  # 判断是否为文件filesize = os.path.getsize(pathTmp)  # 如果是文件，则获取相应文件的大小#print('目录中的子文件大小：%d字节' % filesize)list1.append(filesize)      # 将文件的大小添加到列表print('%s 目录中的文件总大小：%d 字节' % (path, sum(list1)))print('%s 目录中的文件总大小: %.4f MB' % (path, (sum(list1)/1024/1024)))print('%s 目录中的文件总大小: %.4f GB' % (path, (sum(list1)/1024/1024/1024)))path = "D:\\image"
get_size(path)

获取所有磁盘信息

def get_disk_info():disk_used = {}for id in psutil.disk_partitions():if 'cdrom' in id.opts or id.fstype == '':continuedisk_name = id.device.split(':')s = disk_name[0]disk_info = psutil.disk_usage(id.device)#print(disk_info)disk_used[s + '盘使用率：'] = '{}%'.format(disk_info.percent)disk_used[s + '剩余空间：'] = '{}GB'.format(disk_info.free // 1024 // 1024 // 1024)print("sdsds:%s"%disk_used)get_disk_info()

实例：获取D：\image的大小，然后此文件夹会不停的写入文件，当D盘剩余空间小于5GB时，给出警告信息
