Final answer:
Yes, the code provided chains together the strip() and lower() methods to manipulate the user's input.
Step-by-step explanation:
In computer programming, you can chain methods together to perform multiple operations on a single piece of data. In this case, the strip() method removes specified characters from the beginning and end of a string, the lower() method converts all the characters in a string to lowercase, and input() is a built-in function in Python that allows the user to enter data from the keyboard. By chaining these methods together, the code provided will remove any exclamation marks, question marks, or periods from the input and convert it to lowercase.
