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:
How can I determine The numerator and the power from a certain number?
How can I discover or find out which/what number can stand as a numerator and as a power for a certain number for example: 8 is the initial/certain number, but was split to 2 raised to the power of 3 where; Is there a software/algorithm of any sort that can provide an answer to this question for example 64? Answer
Unexpected result in the numerical calculation – (invalid value encountered in double_scalar )
The result is I am having troubling to understand the problem here. It’s clear that I can print the x, but I cannot take the power of it. Meanwhile when I write the code as I get I am literally shocked. I cannot understand what is going on. If I just put the numbers manually I can calculate the result.

Get size in Bytes needed for an integer in Python
How can I find out the number of Bytes a certain integer number takes up to store? E.g. for hexadecimal x00 – xff (or decimal 0 – 255 = binary 0000 0000 – 1111 1111) I’m looking to get 1 (Byte), hexadecimal x100 – xffff (or decimal 256 – 65535 = binary 0000 0001 0000 0000 – 1111 1111 1111
How do I find the difference between two values without knowing which is larger?
I was wondering if there was a function built into Python that can determine the distance between two rational numbers but without me telling it which number is larger. e.g. Obviously I could write a simple definition to calculate which is larger and then just do a simple subtraction: but I’d rather not have to call a custom function like
