1. Question: Write a function that takes a list L and returns a random sublist of size N of that list. Assume that the indexes must be in increasing order. That is, you cannot go backwards Example L [1, 2, 3, 4, 5] 5 The function should return one of these lists: [2, 3, 4] [2, 3, 5] [2, 4, 5] [3, 4, 5]

    Write the function deep_contains. It takes as input a number and a list. That list might contain lists as elements, and those lists might contain lists, etc. The deep_contains' function should return a Boolean indicating whether the number is contained inputted list, or a sublist of it, or a sublist of that, and so forth. For example: deep_contains (3, (1,3,5]) returns True deep_contains(3, 11, [3,5]]) returns True deep_contains (3, 1, [[3,4],5),6]) returns True deep_contains (2, (1,3,5]) returns False This function...

    Problem 1. Write a Python function times_i_at_odd(L) that takes as arguments a list L and returns a list consisting of the elements of L multiplied by the index number of the element at odd positions. (Use list comprehensions) >>> times_i_at_odd([1,2,3,4,5,6,7,8,9,10]) [2, 12, 30, 56, 90] Problem 2. Write a recursive function sum_cols(grid, n) that takes a list of lists of integers grid and integer n and returns the sum of column n in grid.

    Write a function called find_max that takes a two-dimensional list as a parameter and returns the number of the row that sums to the greatest value. For example, if you had the following list of lists: list = [[1, 2, 3], [2, 3, 3], [1, 3, 3]] The first row would be 6, the second 8 and the third 7. The function would, therefore, return 1. You can assume the passed in list of lists has at least one row...

    Write a function called avg_max that takes a list of lists (sublists may be empty) and return the average of the largest item in each sublist as a float. If a sublist is empty, do not consider it for the purposes of computing average. You may assume that everything inside a non-empty sublist is a number. You may assume that at least one sublist will be non-empty. Write a function called avg max that takes a list of lists (sublists...

    1. Make a function make_list_of_lists(n, m) that creates and returns a list of n lists of size m, where each of the m elements in a sublist are randomly generated integers between 1 and 9. For example, you might obtain l = make_list_of_lists(2,2) >>> print(l) [[1, 4], [5, 7]] Big Hint: You can do this using numpy along the lines of the following code: import numpy >>> l = list(numpy.random.randint(a,b,c)) where you need to sort out what the values of...

    Question 1a - Increasing Numbers in List - First Occurence(3 points) Write a function numIncreasing1(L) that takes as input a list of numbers and returns a list of the first sequence within that is increasing order, and has a length of at least 2. If no increasing sequential numbers are found, (ie. the input list is in descending order) then naturally a list of just the first value is returned. Increasing sequence means for a number to be valid it...

    Using Python3 Write a function that takes an array of integers and returns it in increasing order. There can be negative numbers, but they are treated as positive numbers. Example list= list=[-6,7,6,7,-9,1,0,-3,-2,1,4] Answer list= [0, 1, 1, -2, -3, 4, 6, -6, 7, 7, 3]

    Python3: Write the function findLongestStreak(lst) which takes a list of numbers, lst, and returns the longest streak of numbers which occur in the list. A streak of numbers is a list of numbers where each number is one greater than the one that occurred before it- for example, [4, 5, 6, 7]. So findLongestStreak([3, 4, 8, 2, 3, 4, 5, 7, 8, 9]) would return [2, 3, 4, 5]. If there is more than one streak with the longest length,...
