Problem Statement: Use boto3 library in Python to restore all secret keys from specific location in AWS Secret Manager.Approach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_stored_location is the required parameter.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 restore_secret and pass the secret_stored_location as SecretId.Step 6: It returns the metadata of restored secret.Step 7: Handle the generic exception if something ...

Problem Statement: Use boto3 library in Python to create a secret key as plain text 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 is the required parameter. It is a place where secrets are saved with given key-pair value. Make sure secret_key_pair is written as string, not as dict. For example: '{key:pair}'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 ... Read More

Problem Statement: Use boto3 library in Python to paginate through multi-part upload objects of a S3 bucket from AWS Glue Data Catalog that is created in your accountApproach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: prefix_name, max_items, page_size and starting_token is optional parameter for this function while bucket_name is required parameters.Prefix_name is the specific sub folders where user wants to paginate throughmax_items denote the total number of records to return. If the number of available records > max_items, then a NextToken will be provided in the response to resume pagination.page_size denotes the size ... Read More

When it is required to copy all the elements from one array to another, an empty array with ‘None’ elements is created. A simple for loop is used to iterate over the elements, and the ‘=’ operator is used to assign values to the new list.Below is a demonstration of the same −Example Live Demomy_list_1 = [34, 56, 78, 90, 11, 23] my_list_2 = [None] * len(my_list_1) for i in range(0, len(my_list_1)):    my_list_2[i] = my_list_1[i] print("The list is : ") for i in range(0, len(my_list_1)): print(my_list_1[i]) print() print("The new list : ") for i in ...

When it is required to construct a binary tree, and perform operations such as inserting an element, deleting an element and displaying elements of the tree, a class is defined with methods in it. An instance of the class is defined and this is used to access the elements and perform operations.Below is a demonstration of the same −Example Live Democlass Tree_struct:    def __init__(self, data=None, parent=None):       self.key = data       self.children = []       self.parent = parent    def set_root(self, data):       self.key = data    def add_node(self, node): ...

When it is required to check if a number has consecutive zeroes of a specific base, a method is defined, that takes the number and base as parameters, and uses another method to return Yes or No depending on whether the base is present or not.Below is a demonstration of the same −Example Live Demodef check_consecutive_zero(N, K):    my_result = convert_to_base(N, K)    if (check_n(my_result)):       print("Yes")    else:       print("No") def convert_to_base(N, K):    weight = 1    s = 0    while (N != 0):       r = N % K   ...
