fs.path¶
Useful functions for working with PyFilesystem paths.
This is broadly similar to the standard os.path
module but works
with paths in the canonical format expected by all FS objects (that is,
separated by forward slashes and with an optional leading slash).
See Paths for an explanation of PyFilesystem paths.
- fs.path.abspath(path: Text) Text [source]¶
Convert the given path to an absolute path.
Since FS objects have no concept of a current directory, this simply adds a leading
/
character if the path doesn’t already have one.- Parameters:
path (str) – A PyFilesytem path.
- Returns:
An absolute path.
- Return type:
str
- fs.path.basename(path: Text) Text [source]¶
Return the basename of the resource referenced by a path.
This is always equivalent to the ‘tail’ component of the value returned by split(path).
- Parameters:
path (str) – A PyFilesytem path.
- Returns:
the name of the resource at the given path.
- Return type:
str
Example
>>> basename('foo/bar/baz') 'baz' >>> basename('foo/bar') 'bar' >>> basename('foo/bar/') ''
- fs.path.combine(path1: Text, path2: Text) Text [source]¶
Join two paths together.
This is faster than
join()
, but only works when the second path is relative, and there are no back references in either path.- Parameters:
path1 (str) – A PyFilesytem path.
path2 (str) – A PyFilesytem path.
- Returns:
The joint path.
- Return type:
str
Example
>>> combine("foo/bar", "baz") 'foo/bar/baz'
- fs.path.dirname(path: Text) Text [source]¶
Return the parent directory of a path.
This is always equivalent to the ‘head’ component of the value returned by
split(path)
.- Parameters:
path (str) – A PyFilesytem path.
- Returns:
the parent directory of the given path.
- Return type:
str
Example
>>> dirname('foo/bar/baz') 'foo/bar' >>> dirname('/foo/bar') '/foo' >>> dirname('/foo') '/'
- fs.path.forcedir(path: Text) Text [source]¶
Ensure the path ends with a trailing forward slash.
- Parameters:
path (str) – A PyFilesytem path.
- Returns:
The path, ending with a slash.
- Return type:
str
Example
>>> forcedir("foo/bar") 'foo/bar/' >>> forcedir("foo/bar/") 'foo/bar/' >>> forcedir("foo/spam.txt") 'foo/spam.txt/'
- fs.path.frombase(path1: Text, path2: Text) Text [source]¶
Get the final path of
path2
that isn’t inpath1
.- Parameters:
path1 (str) – A PyFilesytem path.
path2 (str) – A PyFilesytem path.
- Returns:
the final part of
path2
.- Return type:
str

>>> isbase('foo/bar', 'foo/bar/baz/egg.txt') True
- fs.path.isdotfile(path: Text) bool [source]¶
Detect if a path references a dot file.
- Parameters:
path (str) – Path to check.
- Returns:
True
if the resource name starts with a'.'
.- Return type:
bool
Example

- fs.path.isparent(path1: Text, path2: Text) bool [source]¶
Check if
path1
is a parent directory ofpath2
.- Parameters:
path1 (str) – A PyFilesytem path.
path2 (str) – A PyFilesytem path.
- Returns:
True
ifpath1
is a parent directory ofpath2
- Return type:
bool
Example
>>> isparent("foo/bar", "foo/bar/spam.txt") True >>> isparent("foo/bar/", "foo/bar") True >>> isparent("foo/barry", "foo/baz/bar") False >>> isparent("foo/bar/baz/", "foo/baz/bar") False
- fs.path.issamedir(path1: Text, path2: Text) bool [source]¶
Check if two paths reference a resource in the same directory.
- Parameters:
path1 (str) – A PyFilesytem path.
path2 (str) – A PyFilesytem path.
- Returns:
True
if the two resources are in the same directory.- Return type:
bool
Example
>>> issamedir("foo/bar/baz.txt", "foo/bar/spam.txt") True >>> issamedir("foo/bar/baz/txt", "spam/eggs/spam.txt") False
- fs.path.iswildcard(path: Text) bool [source]¶
Check if a path ends with a wildcard.
- Parameters:
path (str) – A PyFilesystem path.

True
if path ends with a wildcard.- Return type:
bool
