You will create and submit a single script including each of the following function definitions (see the assignment page in Canvas for a starter script). Remember to pay close attention to whether your result should be return ed or print ed. You should print enough test cases below each of your function definitions to be reasonably sure it works for all types of inputs as described in the problem. Your test cases should be different from any of the examples provided in the problem. FOr all questions on Part 2, you may not use any buill-in functions or methods other than range, len, and append. 1. A list of mumbers is said to be balanced if the sum of its first half is cqual to the sumn of its second half (if the list has odd length, then we ignore the center value in both sums). Write a function is balanced that takes any list of numbers num list and returns True if the

4. Write a function remove_repetition that takes any list 1st and returns a new list with the same entries as 1st , except all instances of consecutive repetition are no longer present. For example, remove_repetition([3, 4, 4, 6, 4, 3, 3, 3, 1]) should return the new 2 list [3, 4, 6, 4, 3, 1] . 5. Write a function n_gram that takes any string word and a positive integer n, and that returns a list containing all adjacent substrings of length n in word For example, n_gram('hello', 2) should return the list ['he', 'el', 'll', 'lo']. and n gram ('science', 5) should return the list ['scien', 'cienc', 'ience']. If n is larger than len (word), then the list returned should be empty.
