Problem Statement: Use boto3 library in Python to paginate through all triggers 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 functionmax_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 NextToken from a previous response.Step 3: Create an AWS session using boto3 ...

When it is required to check if a singly linked list is a palindrome or not, methods to add an element, get the previous node and to check if a palindrome is formed are defined.Below is a demonstration of the same −Example Live Democlass Node: def __init__(self, data): self.data = data self.next = None class LinkedList_struct: def __init__(self): self.head = None self.last_node = None def add_elements(self, data): if self.last_node is None: self.head = Node(data) ...

We are familiar with popup and used it in many applications. Popup in a tkinter application can be created by creating an instance of Toplevel(root) window. For a particular application, we can trigger the popup on a button object.Let us create a Python script to close the underlying or the main window after displaying the popup. We can close the main window while residing in a popup window by using the withdraw() method.ExampleThrough this example, we will create a popup dialog that can be triggered after clicking a button. Once the popup will open, the parent window will close automatically.#Import ... Read More

In order to work with tkinter applications and widgets, we have to import the tkinter library in the environment. There are multiple ways to import the tkinter library in the notebook.Using from tkinter import *Using import tkinter as tkThe first method to import the tkinter library is the most common, as it comes with all the inbuilt methods or functions. In the general sense, we don’t have to explicitly override the method for the widgets. In this way, we can create the object of widgets just by using the widget constructor. It comes with all the modules defined in tkinter.However, ... Read More
When it is required to find tuples that have position elements from a list of tuples, list comprehension can be used.Below is a demonstration of the same −Example Live Demomy_list = [(56, 43), (-31, 21, 23), (51, -65, 26), (24, 56)] print("The list is : ") print(my_list) my_result = [sub for sub in my_list if all(elem >= 0 for elem in sub)] print("The positive elements are : ") print(my_result)OutputThe list is : [(56, 43), (-31, 21, 23), (51, -65, 26), (24, 56)] The positive elements are : [(56, 43), (24, 56)]ExplanationA list of tuples is defined, and is ...

When it is required to find tuples that have elements that are divisible by a specific element ‘K’, the list comprehension can be used.Below is a demonstration of the same −Example Live Demomy_list = [(45, 90, 135), (71, 92, 26), (2, 67, 98)] print("The list is : ") print(my_list) K = 45 print("The value of K has been initialized to ") print(K) my_result = [sub for sub in my_list if all(ele % K == 0 for ele in sub)] print("Elements divisible by K are : " + str(my_result))OutputThe list is : [(45, 90, 135), (71, 92, 26), (2, ...

When it is required to sort the tuples based on the maximum element in it, a method is defined that uses the ‘max’ method to return the highest element.Next the ‘sort’ method can be used to sort the list based on the previously defined function.Below is a demonstration of the same −Example Live Demodef get_max_value(my_val): return max(my_val) my_list = [(4, 6, 8, 1), (13, 21, 42, 56), (7, 1, 9, 0), (1, 2)] print(“The list is : “) print(my_list) my_list.sort(key = get_max_value, reverse = True) print(“The sorted tuples are : “) print(my_list)OutputThe list is : [(4, 6, ...
