You can assume that the two input strings contain only letters and spaces. Sample calls should look like this:>>> are_anagrams ("bimmy is my friend", "My Bird Fey Minims") True>>> are_anagrams ("bimmy is my friend", "hello everyone") False>>> are_anagrams ("internet anagram server", "I rearrangement servant") True>>> are_anagrams ("internet anagram server", "internet anagram server") True 3. find_movies_by_director 4:11 PM This function takes a list of tuples (representing movies) and a string (representing a name of a director) and returns a 65°F Sunny 11/2/2021 e searcharrow_forwardA. The following code in the function "is_prime" attempts to examine a number and return whether the number is prime (i.e. it has no factors besides 1 and itself). It has a "Boolean Flag" called 'prime', however, the boolean logic is not implemented correctly, so the function won't always return the correct answer. # This function determines whether an integer is prime.def is_prime(n):prime = Truefor i in range(2, n): if n2 % i == 0: prime = Falseelse: prime = truereturn prime In what cases does the function report an incorrect answer? How can the code be fixed for it to always report the correct answer? Write your answers as "comments" and the fixed code as a separate python filearrow_forwardCreate a function that takes a number (int) and returns a corresponding string of dashes. Examples: num_to_dashes(1) ➞ "-" num_to_dashes(5) ➞ "-----" num_to_dashes(3) ➞ "---"arrow_forward

- python3 Write a recursive function called is_palindrome(string) that takes a string parameter and checks if it is a palindrome ignoring the spaces, if any, and returns True/False. Sample output:>>> print(is_palindrome("never odd or even"))True>>> print(is_palindrome("step on no pets"))Truearrow_forward// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }arrow_forward***IN PSUEDOCODE ONLY - not a real programming language!!*** Question:A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Design a Boolean function called isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise. Use the function in a program that prompts the user to enter a number and then displays a message indicating whether the number is prime. The following modules should be written: - getNumber, that accepts a Ref to an integer, prompts the user to enter a number, and accepts that input - isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise - showPrime, that accepts an integer as an argument , calls isPrime, and displays a message indicating whether the...arrow_forward
- Ex. 8.4) The following functions are all intended to check whether a string contains any lowercase letters, but at least some of them are wrong. For each function, describe what the function actually does (assuming that the parameter is a string).arrow_forwardConsider the following line of code: X = new int*[n]; What should the type of x be? O int O int* O int** O int& O None of the abovearrow_forwardWrite a function flipCase that accepts a word as an argument and returns the same word but with each upper case letter switched to lower case and vice-versa.
