I’m trying to write a python code that allows me to iteratively sum up the average values of three elements of a list, starting with the third element and its two predecessors. Let me give you an example: I want to calculate the following: Since I’m quite new to programming I couldn’t find an effective way of putting this into

I need to python code to get sum of some of its k consecutive numbers in a list in python
#Given array of integers, find the sum of some of its k consecutive elements. #Sample Input: #inputArray = [2, 3, 5, 1, 6] and k = 2 Answer Your question is not clear but assuming you need a function to return the sum of the highest pair of numbers in your list:
Stuck in this question and couldn’t understand the code for the sum of subarray
I am stuck in the end function part of the question and arr[start]/arr[end] as well I fail to understand the code. The question is as follows: Given an unsorted array A of size N that contains only non-negative integers, find a continuous sub-array which adds to a given number S. You don’t need to read input or print anything. The
When creating a function with summation in it, how do you add terms to the summation? (Python)
I need to find a way to add new terms to the function: f(x) = 4sin(x)/pi such that the new function looks like this: f(x) = 4sin(x)/pi + 4sin(3x)/3pi + 4sin(5x)/5pi + 4sin(7x)/7pi … up to 201. I was thinking I could create the function with a for loop inside that would iterate using a list n but there must
How to ignore numbers after specific number in the list/array in Python?
I’m stuck on this problem: I was trying to return sum of list of numbers in the array ignoring sections of numbers starting with a 6 and extending to the next 9 (every 6 will be followed by at least one 9). Return 0 for no numbers. Here are my test cases: I came up with something like: Answer i
Python: Maximum Subarray Sum
I’ve just tried to start learning Python today, so I am not knowledgeable when it comes to it’s functions. However, I found the maximum subarray problem, and wanted to try and solve it with the few, simple logical commands I have at my disposal. I have gotten stuck, and am almost certain the problem is in my logic and not
Sum of the integers from 1 to n
I’m trying to write a program to add up the numbers from 1 to n. I’ve managed to get it to print the numbers several times but not to add them all. It keeps on just adding two of the numbers. My 1st attempt is: How can I fix this problem? For the recursive version of this question, see Recursive
Sum slices of consecutive values in a NumPy array
Let’s say I have a numpy array a containing 10 values. Just an example situation here, although I would like to repeat the same for an array with length 100. I would like to sum the first 5 values followed by the second 5 values and so on and store them in a new empty list say b. So b
Sum the digits of a number
If I want to find the sum of the digits of a number, i.e.: Input: 932 Output: 14, which is (9 + 3 + 2) What is the fastest way of doing this? I instinctively did: and I found this online: Which is best to use for speed, and are there any other methods which are even faster? Answer Both
Add SUM of values of two LISTS into new LIST
I have the following two lists: Now I want to add the items from both of these lists into a new list. output should be Answer The zip function is useful here, used with a list comprehension. If you have a list of lists (instead of just two lists):
