tuple -> () # tuple is a like a list but you cannot change the values in a tuple once it's defined. Tuples are good for storing information whose elements shouldn't be changed throughout the life of a program. Deque deque is preferred over a list in the cases where we need quicker...
Write a Python program to check if two given lists contain the same elements regardless of order. Use set() on the combination of both lists to find the unique values. Iterate over them with a for loop comparing the count() of each unique value in each list. Return False if the counts...
we will check the size of the list and the set. If the size of both the objects are equal, it will confirm that the list has no duplicate elements. If the size of the set is greater than the list, it will mean that the list contains duplicate elements. We can understand this from...

Hello, codedamn learners! Today, we are going to delve deep into a ubiquitous yet crucial aspect of Python programming: checking if a list is empty. This task may seem trivial, but understanding it thoroughly can make a significant difference in your
Okay, so why did changing the order affect the length of the generated set object? The answer is the lack of intransitive equality only. Since sets are "unordered" collections of unique elements, the order in which elements are inserted shouldn't matter. But in this case, it does matter....
Do a similar thing to create a new variable, upstairs, that contains the last 4 elements of areas. Print both downstairs and upstairs using print(). # Create the areas list areas = ["hallway", 11.25, "kitchen", 18.0, "living room", 20.0, "bedroom", 10.75, "bathroom", 9.50] ...
