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, ...

In this article, we will see how to paginate through security configuration present in AWS Glue.ExampleProblem Statement: Use boto3 library in Python to paginate through security configuration 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.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, ...

When it is required to find the consecutive column difference in a list of tuple, it can be iterated over, and the ‘abs’ method and the ‘append’ method can be used.The ‘abs’ method returns the absolute or positive value, and the append adds elements to a list.Below is a demonstration of the same −Example Live Demomy_list = [(67, 89, 32), (11, 23, 44), (65, 75, 88)] print("The list is : ") print(my_list) print("The value of k has been initialized") K = 1 my_result = [] for idx in range(0, len(my_list) - 1): my_result.append(abs(my_list[idx][K] - my_list[idx + 1][K])) ...

Tkinter Pack Manager acts based on using the extra space within the parent widget. While packing a widget, we can specify whether the widget should shrink or fill in the entire screen. In order to enable the widget to grow in the entire window, we can use the 'fill' property. It helps to fill the widget in the screen by adding “x” as horizontal, “y” as vertical or “BOTH”.Whenever we use expand(boolean) property, then we are generally resizing the widget size to expand in its available space. It takes boolean values as true or false. When the expand property is ... Read More

Tkinter Popup are toplevel window interfaces that wrap up the widget and the element with the main window. It can be embedded in any main window using a handler like Button Widget. Popup can be created using the Toplevel(root) constructor.ExampleIn this example, we will create a simple application containing a Label widget and a button to open the popup message box which contains an Entry field. Once the popup is opened, it can have the functionality to go back to the main window.#Import the required library from tkinter import* #Create an instance of tkinter frame win= Tk() #Define geometry of ...

When it is required to remove tuples from a list of tuples where a ‘None’ element is present, a list comprehension can be used.Below is a demonstration of the same −Example Live Demomy_list = [(2, None, 12), (None, None, None), (23, 64), (121, 13), (None, ), (None, 45, 6)] print("The list is : ") print(my_list) my_result = [sub for sub in my_list if not all(elem == None for elem in sub)] print("The None tuples have been removed, the result is : " ) print(my_result)OutputThe list is : [(2, None, 12), (None, None, None), (23, 64), (121, 13), (None, ...
