here is the function.

Python. Help, please

def decrypt (word list): ''' Test >>> decrypt (test_codes) When will the sun come back >>> decrypt (encrypt('2b or not 2b')) 2b or not 2b pass Exercise 3 del decrypt(word_list): Inputs: a 2 dimensional list Results: prints a sentence or phrase Details: This function takes a sentence that had been encrypted with the exercise 2 function and converts in back into a sentence or phrase. Remember that the chri) function takes a parameter of a character code and returns the actual character: chr(116) When printing, be sure to add a space after each converted word. The template file contains one pre-encrypted phrase (test_codes) for you to test with but you should also create your own test cases using the encrypt function you write for exercise 2 Example output: >>> decrypt (test_codes) When will the sun come back >>> decrypt (encrypt('2b or not 2')) 2b or not 2b def encrypt (phrase): "'' Test >>> encrypt ('When will the sun come back') [[87, 104, 101, 110], [119, 105, 108, 108], [116, 104, 101], [115, 117, 110], [99, 111, 109, 101], [98, 97, 99, 107]] >>> encrypt('Is there room for 1 more?')
