For python 3.

Write a function named start_end_letter that accepts a character (a one-letter string) as a parameter. The function repeatedly prompts the user to enter console input until the user types two consecutive words that both start and end with that letter for example, the word "shells" starts and ends with 's'. The function then prints a message showing the last word typed Your code should be case-insensitive for example, if the character passed is the lowercase 't', you should also consider it a match if the user types a word that starts and ends with an uppercase 'T. If the user types a one-letter word, that word is considered to start and end with its single letter. For example, the word "A" starts and ends with a. The following log represents the console output from a call to your function. (User input is shown like this.) Your function should exactly match the output structure and behavior shown below when given similar input start_end letter('s') Looking for two "s" words in a row Type a word: I Type a word: love Type a word: CS Type a word: students Type a word: PROGRAMS Type a word: SCISSORS Type a word: melon lype a word: pens Type a word: Q Type a word: scores Type a word: S0S "s" is for "SOS" Assumptions: You may assume that the parameter value passed will be a lowercase letter from 'a' to 'z' inclusive. You may also assume that the user will type a valid single-word response to each prompt and that the word will contain at least one character (the user will not type a blank line) Constraints: You should not use any data structures such as arrays to help you solve this problem. You may declare as many simple variables such as ints or strings as you like
