When it is required to sort the elements of an array in descending order, the ‘sort’ method can be used by specifying a parameter named ‘reverse’ to True.Below is a demonstration of the same −Example Live Demomy_list = [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] print("The list is :") print(my_list) my_list.sort(reverse = True) print("The list after sorting is :") print(my_list)OutputThe list is : [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] The list after sorting is : [89, 78, 56, 44, 42, 31, 23, 11, 9, 0]ExplanationA list is defined, and is displayed on the console.The ...

When it is required to sort the elements of an array in ascending order, the ‘sort’ method can be used. It helps sort the elements in ascending order by default. If we want it to be sorted in descending order, a parameter named ‘reverse’ can be set to True.Below is a demonstration of the same −Example Live Demomy_list = [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] print("The list is :") print(my_list) my_list.sort() print("The list after sorting is :") print(my_list)OutputThe list is : [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] The list after sorting is : ...

When it is required to right rotate the elements of a list, the elements are iterated over, and a last element is assigned a value, after which the elements are iterated over, and an element is swapped.Below is a demonstration of the same −Example Live Demomy_list = [31, 42, 13, 34, 85, 0, 99, 1, 3] n = 3 print("The value of n has been initialized to") print(n) print("The list is :") print(my_list) print("List is being right rotated by 3 elements...") for i in range(0, n):    last_elem = my_list[len(my_list)-1]    for j in range(len(my_list)-1, -1, -1):     ...

When it is required to print the elements of a list that are present at even index/position, a loop can be used to iterate over the elements, and only check the even positions in the list by specifying the step size as 2 in the range function.Below is a demonstration of the same −Example Live Demomy_list = [31, 42, 13, 34, 85, 0, 99, 1, 3] print("The list is :") print(my_list) print("The elements in odd positions are : ") for i in range(0, len(my_list), 2):    print(my_list[i])OutputThe list is : [31, 42, 13, 34, 85, 0, 99, 1, 3] The elements ...

When it is required to print the elements of an array in reverse order, the list can be iterated over from the end.Below is a demonstration of the same −Example Live Demomy_list = [21, 32, 43, 54, 75] print("The list is : ") for i in range(0, len(my_list)):    print(my_list[i]) print("The list after reversal is : ") for i in range(len(my_list)-1, -1, -1):    print(my_list[i])OutputThe list is : 21 32 43 54 75 The list after reversal is : 75 54 43 32 21ExplanationA list is defined, and is displayed on the console.The list is iterated over, and displayed.It is reversed ...

When it is required to print the duplicate elements of an array, the list elements are iterated over, and a nested loop is used.Below is a demonstration of the same −Example Live Demomy_list = [1, 2, 5, 6, 8, 9, 3, 4, 8, 9, 1, 8] print("The list is :") print(my_list) print("The duplicate elements in the list are : ") for i in range(0, len(my_list)):    for j in range(i+1, len(my_list)):       if(my_list[i] == my_list[j]):          print(my_list[j])OutputThe list is : [1, 2, 5, 6, 8, 9, 3, 4, 8, 9, 1, 8] The duplicate elements in ...

When it is required to left rotate the elements of an array, the array can be iterated over, and depending on the number of left rotations, the index can be incremented that many times.Below is a demonstration of the same −Example Live Demomy_list = [11, 12, 23, 34, 65] n = 3 print("The list is : ") for i in range(0, len(my_list)):    print(my_list[i]) for i in range(0, n):    first_elem = my_list[0]    for j in range(0, len(my_list)-1):       my_list[j] = my_list[j+1]    my_list[len(my_list)-1] = first_elem print() print("Array after left rotating is ...

Problem Statement: Use boto3 library in Python to find out whether a function can paginate or not in AWS secret.Approach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_function is the required parameter in this function.Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4: Create an AWS client for secretmanager.Step 5: Now use the can_paginate function and pass the parameter secret_function.Step 6: It returns True if the function can paginate; ...

Problem Statement: Use boto3 library in Python to remove tags in AWS secret.Approach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_location and tags_list are the required parameters in this function. tags_list should be the list of keys to be untaged.Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4: Create an AWS client for secretmanager.Step 5: Now use the untag_resource function and pass the parameter secret_location as SecretId and tags_list ...
