Python os.path module examples

Posted on | | Visitors

  1. os.path.abspath(path)
    No matter what you pass into os.path.abspath(), the path is seen as a relative path. It is relative to the directory from where you are executing your code. So the return value will concatenate your current directory with path.

    >>> import os.path
    >>> os.getcwd()
    '/home/int3'
    >>> os.path.abspath('file.txt')
    '/home/int3/file.txt'

  2. os.path.split(path)
    This will split the path into a pair, (head, tail) where tail is the file name and head is the directory name.

    >>> path = '/path/to/file.txt'
    >>> os.path.split(path)
    ('/path/to', 'file.txt')
    >>> os.path.split('/path/to/')
    ('/path/to', '')

  3. os.path.dirname(path)
    Return the directory name. It’s in fact the head in the (head, tail) pair.

    >>> os.path.dirname(path)
    '/path/to'
    >>> os.path.dirname('/path/to/')
    '/path/to'

  4. os.path.basename(path)
    Return the file name. It path ends with \ or /, the return value will be ''. It’s in fact the tail in the (head, tail) pair.

    >>> os.path.basename(path)
    'file.txt'
    >>> os.path.basename('/path/to/')
    ''

  5. os.path.exists(path)
    If the path exists, return

    otherwise, return ```False``` .

    ```
    >>> os.path.exists(path)
    False
    >>> os.path.exists('/home/int3/')
    True

  6. os.path.isfile(path)
    If path is an existed file, return True. Otherwise, return False.

  7. os.path.join(path)
    Join one or more path components intelligently. If a component is an absolute path, all previous components are thrown away and joining continues from the absolute path component.

    >>> os.path.join('/home/', 'file1.txt', 'file2.jpg')
    '/home/file1.txt/file2.jpg'
    >>> os.path.join('/home/', '/usr/', 'file1.txt', 'file2.jpg')
    '/usr/file1.txt/file2.jpg'
