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 describe_secret and pass the secret_stored_location as SecretId.Step 6: It returns the metadata of secrets.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 all 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: max_items, page_size and starting_token are the optional parameters for this function, while bucket_name is the required parameter.max_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 of each page.starting_token helps to paginate, and it uses last key ...

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   ...

When it is required to implement a stack using Python, a stack class is created, and an instance of this class is created. Methods to push, pop elements are defined and the instance is used to call these methods.Below is a demonstration of the same −Example Live Democlass Stack_struct:    def __init__(self):       self.items = []    def check_empty(self):       return self.items == []    def add_elements(self, my_data):       self.items.append(my_data)    def delete_elements(self):       return self.items.pop() my_instance = Stack_struct() while True:    print('Push ')    print('Pop')    print('Quit')   ...
