Problem

• Along the way doing so,

---

• Print the input as a list of strings with the 's' characters still present.

Advice

• If you have not yet check out the string module, we highly recommend you do so.

• If you have not yet also check out the lists module, we highly recommend you do so.

Suggested algorithm

• Prompt and get user-supplied text.

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

• Print that list of words.

• Through accumulation produce a new list, where its elements correspond to the user-supplied words with all occurrences of lower case '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 function lets you produce a tweaked version of its string that replaces all occurence of lower case 's' with nothing?

• What is the nothing string?

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

• Print the lower case 's'-less list.

Note

• Do not print anything other than what is requested.
