- Write a program called p3.py. Write a function called validate() that takes a string as input, validates that it is a single letter, and returns the letter in lowercase.Example:validate(“A”) returns avalidate(“abc”) returns invalid(C++) Question: Write a function string middle(string str)that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd". I'm not getting the correct output. What am I doing incorrectly?uestion 42: Return whether a string consists of a single letter In the function below, return True if the input string parameter consists of a single uppercase letter; otherwise, return False. Most solutions would do this in two logical steps: first testing if the string consists of a single character and, second, testing whether that character is one of the uppercase letters (which can be done by seeing if it is alphabetically between A and Z, inclusive).
- please code in python Write a function that receives a string and a number (n) as parameters and returns a new string that contains only every nth letter from the given string. print(everyNth('banana', 2)) # should return aaaprint(everyNth('carrot', 3)) # should return rtprint(everyNth('pear', 1)) # should return pearWrite a function replace_head_tail that takes a string str1 and replaces the first X and last Y characters of the string and returns the resulting string. For example, replace_head_tail("corona virus", 4, 3) returns "rusna vicoro".Write a c++ function called validate that takes a string and validates that the string does not contain any numbers, then outputs whether the string is valid or not. Write a code that tests the function, by taking the string as an input.
- Write a function sum(x,y) that returns a string indicating what the sum of x and y is. For example, when x=3 and y=17 your function should return the string 'The sum of 3 and 17 is 20.'There are three types of edits that can be performed on strings: insert a character,remove a character, or replace a character. Given two strings, write a function to check if they areone edit (or zero edits) away.EXAMPLEpale, ple -> truepales, pale -> truepale, bale -> truepale, bae -> falseWrite a function that takes a reference to a string as an argument and which converts the string to all uppercase.
- Question 2: Write a Python function called weighted average (), which reads four variables from the keyboard and displays a message with the weighted average. The input variables are: the first note, followed by its weight, and the second note, followed by its weight.The 4 variables given as input are real numbers, and the displayed result is a real number.Write a isPalindrome Function Write a function isPalindrome($str) that returns true if the parameter string is a palindrome (a palindrome is a word or sentence that reads the same forward and backward at the character level). You should ignore non-letter characters when determining if the string is a palindrome. Thus, isPalindrome("A man, a plan, a canal, Panama!") should return true.In C++, write a function isVowel that returns true if a character is a vowel (whether you want to include 'y' as a vowel or not is up to you) and false otherwise. Use this function in a program that asks the user to enter a string of characters and outputs the number of vowels.
