What should be done here?

Question

Python

There is a task from stepik's course:
Write a program that takes as input a rectangular matrix as a sequence of lines ending with a line containing only the string "end" (without quotes)

The program must output a matrix of the same size, with each element in position i, j is equal to the sum of the elements of the first matrix at positions (i-1, j), (i+1, j), (i, j-1), (i, j+1). For extreme characters, the neighboring element is on the opposite side of the matrix.

In the case of a single row/column, the element is itself a neighbor in the corresponding direction.

Found the answer on github: https://github.com/Testudinate/Python/blob/master/...
Who can tell what to do and what the task and code are about?
I want to understand and write myself, but I just don’t understand what to do, please explain to me stupid ...

Answer 1

Did you listen to Stepik's course? Or at least some book on Python opened? It's just not clear where such a problem could arise if there is no understanding of how to solve it? There is another example in front of my eyes. It is not clear what to explain - the condition is formulated extremely clearly and clearly: we enter the matrix, recalculate its elements according to the described rule, and display the result. What is unclear? For each step?

Answer 2

can you please explain the code from the github, I took all the tasks from it and understood it, but this one is too complicated
