Write a program in Python for a basic string extraction.
The program should:
- Display a message stating its goal
- Prompt the user to enter any input
- Extract only the string characters from the input
- Display the extraction in lowercase
- For example, for the input "But, why?!?" the output should be
but why
Remember:
- Do not use more advanced functions than needed.
- Make sure to include comments that explain all your steps
(starts with #).
- Run the program a few times to make sure it executes and meets
all the requirements
