Get you a module that can do both

Define a module sort (i.e., a file sort.py) with the definition mergesort.

When sort is invoked as a main module, you should read a line of input, split it on whitespace (i.e., s.split() with no argument), sort it using mergesort, and print out the sorted list. That is:

[user@sahara ~]$ python -m sort
hello there old friend
['friend', 'hello', 'old', 'there']

The sort code should do nothing when it’s just imported. To test this out, define a module client that imports sort and sorts the letters of the string “antidisestablishmentarianism”. For example:

[user@sahara ~]$ python client.py
['a', 'a', 'a', 'a', 'b', 'd', 'e', 'e', 'h', 'i', 'i', 'i', 'i
', 'i', 'l', 'm', 'm', 'n', 'n', 'n', 'r', 's', 's', 's', 's',
't', 't', 't']
