Python

 matrix = [[2.7, 3.4, 5.2, 6.8],
            [3.6, 5.2, 6.8, 7.5],
            [6.7, 7.5, 8.4, 8.9]]

row = int(input("Enter row :"))
column = int(input("Enter column :"))

lets say if user select 3.6 (matrix[0][1]), then how to print 5.2(matrix[1][1])?

What I have tried:

I have tried

Python

print(matrix[row][column + 1])

but it doesn't work for all selection.

Loop over all rows/columns of the matrix, compare the value with the given choice and print if it is appropriate. In your case: Appropriate= matrix[row][col] >= value ;)
Uups, sorry: Looks like 'next column' is important. In this case it becomes something more complicated in the sense you will not scan the whole matrix but only certain columns and you need first to determine the starting column

You first need to check the values of row and column to ensure they are within the range of rows and columns. Also check that column + 1 is not out of range.
