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

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.
python only define the following function: This function must reset the value of every task in a checklist to False. It accept just one parameter: the checklist object to reset, and it must return the (now modified) checklist object that it was given. Define resetChecklist with 1 parameter Use def to define resetChecklist with 1 parameter Use a return statement Within the definition of resetChecklist with 1 parameter, use return _in at least one place. Use any kind of loop Within the definition of resetChecklist with 1 parameter, use any kind of loop in at least one place.

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):
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] ].
Making a list of numbers from 2 to n Create a function named make-2-n-list that takes in one parameter, the end number. It should return a list of numbers from 2 to that number.(make-2-n-list 30) ➔(2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1718 19 20 21 22 23 24 25 26 27 28 29 30) Hint: make a function that makes the list backwards (easy right-fold pattern), then look at your recursive case and think backwards. Pls use scheme(R5RS) to finish this program!Thank you a lot!
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,
this code should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.
should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list and the input should be given by user. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its user input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.
I need to find the asnwer to this question I do have the code from the lab before I just need to know how to add that one to the other code. 3.9 LAB: Smallest and largest numbers in a list using min and max built-in functions NOTE1: Please make sure you complete previous lab successfully before you proceed with this Lab assignment NOTE2: Make sure to copy and past your code from previous lab into here and update it to complete this lab Write a program that reads a list of integers into a list as long as the integers are greater than zero, then outputs the list values and the smallest and largest integers in the list using min and max built-in functions . Ex: If the input is: 10 5 3 21 2 -6 the output is: [10, 5, 3, 21, 2] 2 and 21 This is the code of the lab before that wants me to add to it.
