# 10.4. `statvfs` — Constants used with `os.statvfs()`

2.6 版后已移除: The `statvfs` module has been removed in Python 3.

The `statvfs` module defines constants so interpreting the result if `os.statvfs()`, which returns a tuple, can be made without remembering “magic numbers.” Each of the constants defined in this module is the index of the entry in the tuple returned by `os.statvfs()` that contains the specified information.

`statvfs.``F_BSIZE`

  Preferred file system block size.

`statvfs.``F_FRSIZE`

  Fundamental file system block size.

`statvfs.``F_BLOCKS`

  Total number of blocks in the filesystem.

`statvfs.``F_BFREE`

  Total number of free blocks.

`statvfs.``F_BAVAIL`

  Free blocks available to non-super user.

`statvfs.``F_FILES`

  Total number of file nodes.

`statvfs.``F_FFREE`

  Total number of free file nodes.

`statvfs.``F_FAVAIL`

  Free nodes available to non-super user.

`statvfs.``F_FLAG`

  Flags. System dependent: see `statvfs()` man page.

`statvfs.``F_NAMEMAX`

  Maximum file name length.
