Write a function successor(items, target) that finds the first occurrence of target in the list list items and then returns the item immediately after it. If the target item is the last item in the list or is not present in the list, return None. Check the test cases for how the function should work. Note: Your answer must use a for loop. You are not allowed to use a while loop. For example: Test Result nums = [10, 20, 30] next_num = successor(nums, 20) print (next_num) 30 pets = ['dog', 'cat', 'fish', 'cat', 'dog', 'iguana'] fish after_cat = successor(pets, 'cat') print(after_cat) empty = [] after12 = successor(empty, 12) None print(after12) nums = [4, 7, -1, 12, 9, -1, 11, -1, 8] after8 = successor(nums, 8) print (after8) None

1) Write a function that takes one argument, a list named sample-list. 2 ) If the length of the sample-list is > 8, then use the last element of sample-list and return it in a list. 3) If the length of sample-list is <= 8 and > 4, then return the first elements of sample-list in a list. 4) Otherwise, return the string “This is the third option.”. Please make sure to test your function!!! and explain your code shortly by adding comments to each line.
page WITH Write a function swap() that takes as input a list of items. If the list is not empty, it swaps its first and last elements. The function does not return anything. Sample result with list1= ['all', 'good', 'things', 'must', 'end', 'here'] after the function call list1 becomes: ['here', 'good', 'things', 'must', 'end', 'all'] Write 2 assert statements. www def swap(...): param: ... returns None if_name__ == "__main__": assert ... #TODO: complete your own assert
JS Write a function named find_value that takes a list/array of whole numbers as a parameter. Your functio will need to find if the parameter contains the value 3 as an entry. Return true if the input has an entry equivalent to 3 and false if it does not.
Write the in_order() function, which has a list of integers as a parameter, and returns True if the integers are sorted (in order from low to high) or False otherwise. The program outputs "In order" if the list is sorted, or "Not in order" if the list is not sorted. Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 3], then the function returns False and the program outputs: Not in order Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 10], then the function returns True and the program outputs: In order Note: Use a for loop. DO NOT use sorted() or sort(). python please
Write a function little_sum (number_list, limit) that returns the sum of only the numbers in number_list that are less than or equal to the given limit. In this question you must use a for loop and you are not allowed to use the sum function. For example: Test Result numbers = [1, 2, 3, 4, 5, 6] total = little_sum(numbers, 3) print(total) values = [6, 3, 4, 1, 5, 2] 10 total = little_sum(values, 4) print(total)
Write a function count_evens(nums) that takes a list of ints called nums and returns the number of even ints in the given list. Note: the % "mod" operator computes the remainder, e.g. 5 % 2 is 1.
have been given a singly linked list of integers. Write a function that returns the index/position of integer data denoted by 'N' (if it exists). Return -1 otherwise. Note :Assume that the Indexing for the singly linked list always starts from 0.Input format :The first line contains an Integer 'T' which denotes the number of test cases. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line contains the integer value 'N'. It denotes the data to be searched in the given singly linked list. Remember/Consider :While specifying the list elements for input, -1 indicates the end of the singly linked list and hence -1 would never be a list element. Output format :For each test case, return the index/position of 'N' in the singly linked list. Return -1, otherwise. Output for every test case will be printed in a separate line. Note:You do not need to print anything; it has already been taken care of. Just implement…

PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep def search_words(data, search_words):
In this problem, you have available to you a working version of the function round_up described in part (a). It is located in a module named foo. Using the given round_up function, write a function round_up_all that takes a list of integers and MODIFIES the list so that each number is replaced by the result of calling round_up_ on that number. For example, if you run the code, 1st = [43, 137, 99, 501, 300, 275] round_up_all(1st) print(1st) the list would contain the values [100, 200, 100, 600, 300, 300] Do not re-implement the round_up function, just import the food module and use it. Here is the code for the round_up function that can be imported using foo: def round_up(num): if num % 100 == 0 : #if number is complete divisible return num #return orginal num else: return num + (100-(num % 100)) #else add 100-remainder to num, if __name__ == '__main__': print(round_up(234)) print(round_up(465)) print(round_up(400)) print(round_up(89))
I am very confused on how to answer this and any thing will help. Create a function that accepts a single list. Inside the function, have nested for loops (a for loop inside a for loop). The outer for loop iterates through every item in the list. The inner loop iterates through every subitem in item, and prints it. Test the function by passing it the list [ [0, 1, 2], [3, 4, 5], [6, 7, 8] ].
b. Write a function cut12 that removes the last two items from a list given as its argument. The existing list should be changed in-place; the function should not return anything,
