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 ...

Problem Statement: Use boto3 library in Python to store a new secret in a specific location in AWS Secret ManagerApproach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_stored_location and secret_key_pair are the required parameters. Make sure secret_key_pair is written as string, not as dict.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: Call put_secret_value and pass the secret_stored_location as SecretId and secret_key_pair ...

In this post, we will understand the difference between Stack and HeapStackIt is a linear data structure.Memory is allocated in a contiguous (continuous) block.The memory for a stack is allocated and deallocated automatically using the instructions of the compiler.It costs less to build and maintain a stack.It is easy to implement.It is fixed in size; hence it is not flexible.Its only disadvantage is the shortage of memory, since it is fixed in size.If all the blocks are not occupied, memory gets wasted too.It takes less time to access the elements of a stack.It has an excellent locality of reference.HeapIt is ...
