Python os Module
================

os.path
=======

Find current path:

.. code-block:: python

    # Import the os module
    import os

    # Get the current working directory
    cwd = os.getcwd()

Change path:

.. code-block:: python

    # Import the os module
    import os

    # Change the current working directory
    os.chdir('/tmp')

The argument provided to the chdir() method must be a directory; otherwise NotADirectoryError exception is raised. If the specified directory doesn’t exist, a FileNotFoundError exception is raised. If the user under which the script is running doesn’t have the necessary permissions, a PermissionError exception is raised.

.. code-block:: python

    # Import the os module
    import os

    path = '/var/www'

    try:
        os.chdir(path)
        print("Current working directory: {0}".format(os.getcwd()))
    except FileNotFoundError:
        print("Directory: {0} does not exist".format(path))
    except NotADirectoryError:
        print("{0} is not a directory".format(path))
    except PermissionError:
        print("You do not have permissions to change to {0}".format(path))
