I have the following list: I want to calculate the average of the items which have the same “first and the second elements”. E.g., from the below example, I want to take the average of the elements which have ‘5’ and ‘1’ in the first two elements of the list. So, my desired output should be like this: If I

how to move specific part of a 2d array to either left right up or down?
I know that you can move an array with NumPy so if you use np.roll you can shift array to right or to the left. I was wondering how to move a specific set of values with in the array to either left right up or down. for example if I wanted to move what is circled in red to
What is wrong my python code, I’m trying to add implement multiple file search criteria for files
I want to make changes in my code so I can search for multiple input files and type multiple inputs, let’s say if client order number 7896547 exist in the input file I put there. What is the best way to implement multiple search criteria for multiple files. What I meant is giving around let’s say like more than 50
Remove elements from tuple array that have same value in first index position of each element
Lets say I have a list: There are two tuples with ‘a’ as the first element, and two tuples with ‘c’ as the first element. I want to only keep the first instance of each, so I end up with: How can I achieve that? Answer You can use a dictionary to help you filter the duplicate keys:
How can i represent a 2d array in 3d in phython?

Filtering out rows in multidimensional numpy arrays
Let’s say that I have an array like this: I want to filter out all rows that include negative numbers in them. And, hopefully, get this: I tried this so far: But as you can see I get 1-dimensional array and I am getting unwanted rows (in this case is [2, 2]) How can I do this without using any
Calculate the cumulative sum of multiplying each element of one array by all the elements of a second array
I need to efficiently calculate the running sum of multiplying the elements of one array by all the elements of a second array. It is probably easiest to explain what I am trying to do with code: My ‘a’ array will typically be big so I would like this to run as fast as possible, but right now it is
Array input into an equation get array output in Python
I’m a python beginner and I’m trying to solve a cubic equation with two independent variables and one dependent variable. Here is the equation, which I am trying to solve for v: 3pv^3ā(p+8t)v^2+9vā3=0 If I set p and t as individual values, I can solve the equation with my current code. But what I would like to do is set
How to get multiple sentences in arrays into a single response in python?
As a hobby, I started doing a project with amazon textract which helps in extracting text from a photo or a pdf. Now I ran into a problem. According to what I read from it’s docs, every word in the photo is a small “block”. When I try printing, it prints fine, but if I have to use that text
