Program aeschylus.py

Algorithm to be followed

• Prompt and gets user-supplied text.

• Splits the user-supplied text into a list of words

• Prints the list of user-supplied words.

• Through accumulation, produces a new list whose elements are those of the user-supplied words with all occurrences of "s" removed. To do this, you need to be able to answer the following.

• What type of object is the accumulator? The answer tells you how to set its initial value.

• Where should the accumulator be initialized? Before, in, or after the loop?

• What string member function lets you produce a tweaked version of its string that replaces "s" ' s with nothing? And what is nothining in this case?

• What list member function allows you to append an element to its list?

• Prints the s-less list.

• Reprints the list of user-supplied words.

Solution requirement

• Do not print anything other than what is requested.
