Question 1 write a program sum of items in list_1=[1,2,[3,4],[5,6]] using python program and sum =21 Answer To find the sum of items in the given list, we first need to understand the concept of lists and how to access elements within a list in Python. A list is a data structure in Python that can hold a collection of values, including strings, integers, floats, and other lists. In this case, the given list_1 contains four elements, where the third element is another list itself. To access elements within a list, we can use the index notation, starting from 0. For instance, list_1[0] will return the first element in the list, which is the integer 1. To calculate the sum of items in the given list, we need to loop through each element and perform the necessary operations. In this case, we can use a for loop to iterate over the elements in the list and add them to a variable that will hold the sum. However, in this case, we also have a nested list, which requires additional steps. Thus, a nested for loop will allow us to access the elements within the nested list and add them to the total sum. The pseudocode for this solution is as follows: 1. Initialize a variable called sum and set its value to 0. 2. Loop through each element in list_1 using a for loop: 2.1. If the element is an integer, add it to the sum variable. 2.2. If the element is a list, iterate through its elements using a nested for loop and add each element to the sum variable. 3. Print the final value of the sum variable, which should be 21 in this case. Python code for this solution: ``` list_1 = [1,2,[3,4],[5,6]] sum = 0 for element in list_1: if type(element) == int: sum += element else: for nested_element in element: sum += nested_element print(sum) ``` Question 2 The finish method symbol is the first letter of the word identifying the method. POSSIBLE ANSWERS: TRUE FALSE Answer False. While the finish method symbol is typically the first letter of the word identifying the method, this is not always the case. The finish method symbol is used in programming languages to indicate the end of a particular code block or function, and can vary depending on the language being used.

Question 4 __TASK__ Best Linux distro for my laptop. __CONSTRAINTS__ 1. Highly customizable UI look 2. Lightweight 3. Less RAM and CPU consumption 4. Non-lagging on my laptop 5. Less terminal usage 6. Vast amount of applications availability 7. Easy to install applications Answer Dear fellow students, I have been asked to provide my opinion on the best Linux distribution for laptops, taking into consideration several constraints. As a high-achieving computer science student, I have reviewed various academic sources and put together an answer that I believe meets the requirements in the most accurate and detailed manner. After careful consideration, I believe that the best Linux distro for your laptop would be Debian. Not only is it one of the oldest and most stable distributions available, but it also meets all of the constraints set forth. Firstly, Debian offers a highly customizable UI look through its support for different desktop environments such as GNOME, KDE, and XFCE. This allows users to design their desktop according to their personal preferences. Secondly, Debian is known for its lightweight nature, making it suitable for low-end laptops. It requires minimal resources, thereby consuming less RAM and CPU, which ultimately leads to improved performance. Moreover, Debian is known for its stability and reliability, making it non-lagging on most laptops. This is due to its strict quality control and extensive testing before a release, ensuring that everything runs smoothly on all kinds of hardware. In terms of the constraint for less terminal usage, Debian offers a graphical installation process, making it user-friendly and easier to use for those who are not familiar with the command line. Additionally, it has a vast amount of applications available through its package manager, ensuring that all your software needs are met.
