Here is the solution to the problem

.. code:: python

    !/usr/bin/env python
 
    import pwd
  
    total_list = pwd.getpwall()  # a list of all password database entries
    for i in total_list:  # iterating throgh the list
        if i[5].find("home") == 1:  # if 'home' is present in the user home directory
            print i[0]  # print the user name
        if i[5].find("root") == 1:  # if 'root' is present in the user home directory
            print i[0]  # print the user name

To run the script, follow the steps.

1. Change the file's permissions and make it executable::
