of numbers Write a function named "freq(1) that takes a list 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 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
Write a function named `freq(l)` that takes a list `l` 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
The function list_combination takes two lists as arguments, list_one and list_two. Return from the function the combination of both lists - that is, a single list such that it alternately takes elements from both lists starting from list_one. You can assume that both list_one and list_two will be of equal lengths. As an example if list_one = [1,3,5] and if list_two = [2,4,6]. The function must return [1,2,3,4,5,6].
Write a function find_plateaus that receives a list of integers as parameters.Your function should find and return a list of plateaus, which are numbers that are equal to both of its neighbors. IMPORTANT NOTES: the first and last values can not be plateaus; the plateaus should be in the order they appear in the original list; the same value might be a plateau in multiple places in the original list; there might be no plateaus, in which case you should simply return an empty list. Example 1:If the function call is: find_plateaus([1, 2, 2, 2, 1]) You should return [2], because: 2 == 2 and 2 == 2. Example 2:If the function call is: find_plateaus([10, 2, 20, 4, 4, 4, 5, 8, 5, 5, 5, 5]) You should return [4, 5, 5], because: 4 == 4 and 4 == 4; 5 == 5 and 5 == 5; 5 == 5 and 5 == 5
Write a function called `filler(A, l)` that takes an integer `A`, and a list of integers `l` and if some of the numbers in `l` sum up to `A` then it returns a list of these numbers. Otherwise, it returns `None`. For example, filler(5, [1,6,3,4]) returns [1,4]. filler(5, [1,6,3,7]) returns None. filler(0, [-1,-1,2,-3]) returns [-1,-1,2]. filler(10, [2,3,2,3,1]) returns [2,3,2,3]. If there are multiple answers, then return any of them. You can use each number in the list once for each occurence. """ def filler(A, l): # remove the following line to solve this question return
Write a function verifsort that accepts a list as a parameter, check if the list elements are sorted and returns: 1 - if the list is sorted in ascending order, 2 – if the list is sorted in descending order, and 0 – if the list is not sorted. Write a function listsort which accepts a list as a parameter, and sorts it in ascending order. You can use any standard sorting algorithm, but don’t use built-in sort methods and functions. The function must sort and return the list. Write a script that asks user to enter 10 integer numbers, creates a list from those numbers, then calls verifsort function to detect if this list is sorted, prints message (list is sorted or list is not sorted) and if it’s not sorted then calls listsort function and prints the sorted list after listsort
The following program reads two lines of input from the keyboard. The first line is a bicycle wheel circumference in centimetres. The second line consists of a number of times in milliseconds, separated by a comma, at which a fixed point on the bicycle wheel passes between the forks. The program computes the speed of the bicycle from each pair of times and prints a table of the results. Rewrite the program so that it behaves exactly the same but is pylint compliant, with the additional constraint that no function body can have more than 6 statements. (The function def line, blank lines and comments do not count as statements.) The only permitted global code (that is, code lines that are not indented) are the module docstring, function def lines and the call to your main function. All other code (assignment statements, if statements, loops etc) must be within function bodies. Note that docstrings are required for pylint compliance, but you do not need to make them meaningful.…
Write a function convert_to_millimetres (measurements) which takes a list of measurements in centimetres as a parameter and modifies that list by replacing each measurement with its millimetres version, which involves multiplying by 10. You will need to use the updated-list pattern. (Note that there's no need to return anything because the function modifies the original list it was given.) For example: Test Result measurements = [10.0, 25.0, 1.0] convert_to_millimetres(measurements) print (measurements) [30.0, 75.0, 3.0]
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.

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)
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.
