Write a function flat_list() which takes a list that contains unknown number of lists. This function takes each list and appends all members to a new list also make sure that the new list elements should be unique. Then, it will sort the list and return the sorted list. Write Python statements that test your function. Part-1: Sample list= [[1, 2, 3], [2, 3, 4], [8, 1], [6] Result= [1, 2, 3, 4, 6, 8]

Step by step
Solved in 2 steps
- Please answer it in Python Write a function extrait_pairs that takes as an argument a list l1 and returns the list obtained from l1 keeping only the even integers (and without changing their order). Be careful, l1 must not be modified by the function. Example: extrait_pairs([4, 7, 12, 0, 3]) is [4, 12, 0] and extrait_pairs([21, 17, 3]) is [ ].Please answer it in Python Write a function min_pair that takes a list as an argument and returns the smallest even integer contained in the list. If the list contains no even integers, the function will return None. Example: min_pairs([4, 7, 12, 0, 21, 5]) is 0 min_pairs([9, 3, 1]) is None. min_pair([16, 13, 10, 102, 7, 23]) is 10Please write it in Python Write a delete function that takes as an argument a list l and an elem element and returns the list obtained from l by deleting all occurrences of elem. Example: delete([4, 7, 12, 4, 4, 0, 4, 5], 4) return => [7, 12, 0, 5]. Write a function insere_milieu that takes as an argument a list l and an element elem and returns the list obtained from l by adding elem "in the middle" of l, that is: If the length of l is even, the item is added once, in the middle of the list. If the length of l is odd: the element is added on either side of the central element. Example: insere_milieu([4, 7, 12, 3], 0) return => [4, 7, 0, 12, 3] and insere_milieu([9, 3, 5, 6, 2], 1) return => [9, 3, 1, 5, 1, 6, 2]. Write a cutting function that takes as an argument a list of numbers l and a threshold number and returns two lists: the first is obtained from l keeping only the numbers below or equal to the threshold; the second is obtained from l keeping only the…

Example: decale([4, 17, 12], 3) is [7, 20, 15]. Write a function intercale_zeros that takes as an argument a list l and returns the list obtained from l by inserting a zero after each element of l. Example: intercale_zeros([4, 17, 12]) is [4, 0, 17, 0, 12, 0].Write a function that takes a list removal(L), delete from it all the elements whose indicesare divisible by 3. And return the resulting list after removing unwanted elements.Example:>>>removal(['A', 'B', 'C', 'D', 'E'])['B', 'C','E'
- PYTHON Write a function called check_third_element that takes in a list of tuples, lst_tups as a parameter. Tuples must have at least 3 items. Return a new list that contains the third element of each tuple. For example, check_third_element([(1,2.2,3.3),(-1,-2,-3),(0,0,0)]) would return [3.3, -3, 0].Write a Python Code for the given function and conditions: Given function: def insert(self, newElement) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.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)
- Write python code 1) 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 Python function that takes in a list of integers (nums) and finds whether the list consists of any duplicate numbers, the function returns True or False accordingly (Note: this is not a linked list, just a Python list). Function must run in place and cannot use Python’s built-in Set() structure. Make sure to provide the most efficient algorithm in terms of its time and space complexity.Python Write a function revers_all (sequence) that takes an arbitrary nested list sequence with arbitrary elements and returns a new list that has the same nested structure, but where all lists both at the top level and at all nested levels are reserved ("backwards") examplereverse_all ([1, 2, 3, [4, 5, ['x', 7]], 8]) becomes[8, [[7, 'x'], 5, 4], 3, 2, 1] I sent parameters can not be changed. It is thus a completely new list to be returned.It is allowed to solve the task recursively or itrelatively or with a compilation of these methods. Your function may not make any readings or printouts Use this program to test import copy sequence = eval(input()) seq_copy = copy.deepcopy(sequence) result = reverse_all(sequence) print (result) if results is sequence: print("Your function does not create a new list") if sequence != seq_copy: print("Your function changes in that submission list")
