write a python function that replaces the None values with the average from that column. example: def replace_with _mean(datalist): •....... returm [] replace_with _mean([['a', 'b'], [1, -2], [-3, 4], [None, 6], [7, 8]]) | output: [1.6666666666666667, 4.0] replace_with mean([['e', 'f, 'g'], [None, 2, 3], [None, -4, -2], [None, 8, 9]]) output: [None, 2.0, 3.333333333333333]

Please answer it in Python Write a function pairsbypairslist that would return pair by pair from the smallest value to the biggest value For example [12, 13, 11, 15], # return : (11, 12) and (13, 15) [9, 15, 4, 24, 19, 2] # return : (2,4) (9,15) (19,24) [1, 5, 9, 15, 21, 9, 12, 9], # return : (1,5) (9,9) (9,12) (15,21)
Write a program in python with a function isPal(L), where L is a list of integers, and the function returns True if the list is a palindrome, False otherwise. For example [5, 2, 9, 9, 2 5] is a palindrome. Use the reverse() method of list and check if the reversed list is the same as the original list.
Write a Python function countEvens that consumes an integer N and a nested list representing a matrix of arbitrary size (but larger than NxN). The function returns the number of even numbers in the NxN sub-matrix of the first N rows and columns. Note: You may assume the list argument passed to the function is a nested list of integers, but it may be larger than NxN!
Write a Python function that will ask the user for an integer X bigger than 20 and return a list "ls" of 10 distinct random integers taken between the interval 0, to X. None of the 10 elements of "ls" should be repeated.
Write a python function named replaceVal(list, valToBeReplaced, newValue) which takesthe above described inputs and finds the value ‘valToBeReplaced’ in the list. If it ispresent, it is replaced with newValue and the updated list is returned, otherwise thesame list is returned.Example:[1,2,3,4,5], 5, 20Output: [1,2,3,4,20] Example:[10, 15, 20, 25, 30], 5, 20Output: [10, 15, 20, 25, 30]
In python, remove_from_list(my_list, indices): Takes two lists as input. Creates a new list from the first input list by removing the elements at indices given by the integers in the second input list, then return the new list. The indices in the second input list may have any order. For example, if the first input list is [4, 8, 12, 16], and the second input list is [0, 2], then the new list returned from the function should have the 4 and the 12 removed, because they were at indices 0 and 2 of the original list. Note: You do not need to consider negative indices for this function. >>> remove_from_list(['abc', 'def', 'ghi'], [1]) ['abc', 'ghi'] >>> strs = ['The', 'quick', 'brown', 'fox'] >>> remove_from_list(strs, [0, 3]) ['quick', 'brown'] >>> strs ['The', 'quick', 'brown', 'fox'] # original list is unchanged >>> remove_from_list(['The', 'quick', 'brown', 'fox'], [3, 0]) ['quick', 'brown']
Write a Python function `removeDuplicates(myList)` that removes duplicate values from a list. While the algorithm for this problem might seem trivial, its implementation is not. In general, it is not advisable to modify a list while you are iterating on it, as in the following pseudo-code: for element in myList: if <condition>: <remove element(s) from myList> # recipe for disaster

Write a python function MedianWithoutHL(ScoreList) that takes an unsorted list of n numbers as a parameter, discards the highest and the lowest numbers and return the median. You can assume the number of items in the list is between 0.0 and 9.9. To find the median from a list of items, you have to sort the list and find out the value of the item in the middle.Note: If the list has an odd number of items, the median is the value of the middle item. If the list has an even number of items, the median is the average of the two middle items.Sample Run #1:scoreList1 = [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]print("The Original ScoreList: ", scoreList1)print(MedianWithoutHL(scoreList1))Output of Sample Run #1:The Original ScoreList: [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]The List after sorting: [5.0, 6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0, 9.5]Without the High & Low: [6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0]7.75
Please help me with this: using js create an array of 30 random numbers that range between 1and 100. And yet again, write a function that will receive a number from the userand determine if that number exists in the array or not. But this time, start bySORTING your input list. After a sort, the list in problem 1 is as follows:[2, 2, 3, 5, 12, 14, 14, 15, 23, 36, 39, 41, 44, 44, 45, 48,49, 50, 52, 52, 59, 71, 81, 82, 88, 89, 89, 93, 96, 97] Approach: Implement a method called findC(x, A, i, j), where x is the number we arelooking for in array A, the first index of the array is i and the last index is j. We wantto determine whether x exists in A anywhere between index i and index j. Your firstcall to this method will therefore look like this: findC(x, A, 0, A.length-1). In the body of your function, compare x with the item that is in the middle of thearray, as you did before. As before, call the middle of index of the array mid. But thistime, if x<=a[mid], recursively call your…
Write a program in PYTHON with a function max(L) which examines the argument list L, and returns the largest object of type float. If there is no float object in the list, then the function returns None. For example,max([100, 'blue', 3.5, 'sugar on the rocks', 7.0]) would return 7.0, andmax([7, 2, 9, 1]) would return None. Note that type(element) == float is a way to check if element is a float
