python检测空间储存剩余大小和指定文件夹内存占用的实例

1、检测指定路径下所有文件所占用内存

import os
def check_memory(path, style='M'):
i = 0
for dirpath, dirname, filename in os.walk(path):
 for ii in filename:
  i += os.path.getsize(os.path.join(dirpath,ii))
if style == 'M':
 memory = i / 1024. / 1024.
 print '％.2f MB' ％ memory
else:
 memory = i / 1024. / 1024./ 1024.
 print '％.4f GB' ％ memory

2、检测指定路径剩余储存空间大小

import ctypes
import os
import platform
import sys
def get_free_space_mb(folder):
""" Return folder/drive free space (in bytes)
"""
if platform.system() == 'Windows':
 free_bytes = ctypes.c_ulonglong(0)
 ctypes.windll.kernel32.GetDiskFreeSpaceExW(ctypes.c_wchar_p(folder), None, None, ctypes.pointer(free_bytes))
 return free_bytes.value/1024/1024/1024
else:
 st = os.statvfs(folder)
 return st.f_bavail * st.f_frsize/1024/1024/1024.

这个适用于unix系统下，windows系统下 os 无 statvfs 属性。

def disk_stat(path):
import os
hd={}
disk = os.statvfs(path)
percent = (disk.f_blocks - disk.f_bfree) * 100 / (disk.f_blocks -disk.f_bfree + disk.f_bavail) + 1
return percent
print disk_stat('.')
