Question
Write a function called match_words() that takes three input parameters; a list of strings of any length (e.g., ['789', 'del','a', 'do', ‘abc’,'bb','dcc']), a character c and an integer x. This function returns a list of all strings in the 2-D list that starts with the character c and is at most x characters long.
Sample run, >>> alist = ['6789', 'black', 'green', 'd', 'blue', 'red', 'beige', 'dddd', 'yellow', 'buff', 'zzzzzzzzz'] >>> print( match_words( alist, ‘b’, 4 )) ['blue’, ‘buff’]

- -python- Write a function called get_words that takes a list of words and a letter,and returns a new list, which only contains the words that don't have the given letter in them. For example, get_words(["cat", "dog"], 'o') should return ["cat"] and get_words(["cat", "bat"], 'a') should return an empty list.arrow_forwardWrite a function sum67 that takes a list as an input parameter and returns the sum of the numbers in the list, except ignore sections of numbers starting with a 6 and extending to the next 7 (every 6 will be followed by at least one 7). Return 0 for no numbers.arrow_forwardDefine a function named get_encrypted_list (word) which takes a word as a parameter. The function returns a list of characters. The first element is the first letter from the parameter word and the rest is as a sequence of '*', each '*' representing a letter in the parameter word. Note: you can assume that the parameter word is not empty. For example: Test Result ['h', ¹*¹ **', '*'] *** guess = get_encrypted_list('hello') print (guess) print (type (guess)) guess = get_encrypted_list('succeed') ['s', '*', print (guess) **']arrow_forward
