Write a function countdown321 (nums) that returns True if the sequence 3, 2, 1 appears in the list nums somewhere and False otherwise. The numbers 3, 2, and 1 must appear contiguously, i.e. with no intervening numbers. You may assume that nums contains at least one element. For example: Test Result sequence = [3, 3, 2, 1, 3] print(countdown321 ( sequence)) True values = [3, 3, 2, 8, 3] False print (countdown321 (values)) print (countdown321 ( [3, 2])) False

Write the following function to sort a list of points on their y-coordinates. Each point is a list of two values for x- and y- coordinates. # Returns a new list of points sorted on the y-coordinatesdef sort(points):For example, the points [[4, 2], [1, 7], [4, 5], [1, 2], [1, 1], [4, 1]] will be sortedto [[1, 1], [4, 1], [1, 2], [4, 2], [4, 5], [1, 7]]. Write a test program that displaysthe sorted result for points [[4, 34], [1, 7.5], [4, 8.5], [1, -4.5], [1, 4.5],[4, 6.6]] using print(list).
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)
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…
Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…
Write a function named 'freq(I) that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example, freq([1,2,3,1,2,1,2,3,1,2]) will return ([1,2], 4) because both 1 and 2 appear 4 times in the list. def freq(1): # remove the following line to solve this question return
Write a function called myunion that will take two lists x and y, and return a list that has the elements of x, followed by the elements of y that are not found in x. For example: (myunion ’(1 3 5 7 9) ’(1 2 3 4 5 6 7)) should return (1 3 5 7 9 2 4 6).
1.Given the argument passed to the function is a list containing integer values, what does the function return def mystery1(someListOfValues: list):total = 0for value in someListOfValues:total += valuereturn total/len(someListOfValues) 2. The function below is to find the largest value in a list passed by parameter. Does it work as intened (yes or no)? If not give an example of an argument it would not work for. def maxValue(someListOfValues:list):"""returns the largest value the list passed by parameter"""value = 0for num in someListOfValues:if num > value:value = numreturn value 3.Write a function called loadNames() that will open a file called names.txt and build a list of its contents and return it. Function Call: names = loadNames()print(names) Sample ouput: ['Nolan Rafaj\n', 'Brandon Brzuszkiewicz\n', 'Amanda Vozari\n', 'Chase Harper\n', 'Bryce Conner']
Write a function named 'freq(I)` that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example, freq([1,2,3,1,2,1,2,3,1,2]) will return ([1,2], 4) because both 1 and 2 appear 4 times in the list. def freq(l): # remove the following line to solve this question return
IN PYTHON PLEASE Write a function def sameSet(a, b) that checks whether two lists have the same ele- ments in some order, ignoring duplicates. For example, the two lists 149 16 9 7 4 9 11 and 11 11 7 9 16 4 1 would be considered identical. You will probably need one or more helper functions.
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.
Write a function set_elements() that assigns 1 to the last and fifth elements of a list parameter. Ex: If the input is: One man's trash is another man's treasure then the output is: ['One', "man's", 'trash', 'is', 1, "man's", 1] ''' Your code goes here ''' vals_to_update = input().split() set_elements(vals_to_update) print(vals_to_update)
