How do you correct, 'TypeError: Unicode-objects must be encoded before hashing'?

When you import 'hashlib' in Python and try to run the following statement you would get an error as shown:
----------
>>> print (hashlib.sha256("Hello World").hexdigest())
Traceback (most recent call last):
  File "", line 1, in
    print (hashlib.sha256("Hello World").hexdigest())
TypeError: Unicode-objects must be encoded before hashing
-----------

There are two ways you can correct this error:
---------
>>> print (hashlib.sha256(b"Hello World").hexdigest())
