Please write a Python code

1. Your program should use a list to store the sentences input by user(the list should be able to store any number of sentences added by user).
2. The inputs to the list will be ended by the user by answering a question about whether they want to add any additional sentences to the list. The user will answer yes or no; however, you dont know what letter case will be used to enter the answer. Also, the user may just enter the first letter for their response. You can only use a single condition (in an IF statement or loop condition) to determine whether to end input or continue (hint: use a string manipulation command to help with this).
3. Once the list has been populated, ask the user which sentence in the list they want to extract a word from and which number word they wish to extract. (dont have to account for the potential that the user enters a sentence number or word number that doesnt exist. ) Once you have these two inputs, youll need to get the right sentence from the list and then get the right word from that sentence.
4. you will then print the word, centered, within a 20-character field with asterisks (*) on either side in the remaining character slots that arent occupied by the word (********best********)
