如何在二维数组的每个单元格中找到数值相同的行？

def find_same_rows(matrix):
    rows = len(matrix)
    cols = len(matrix[0])
    result = []

    for i in range(rows):
        for j in range(cols):
            current_val = matrix[i][j]
            found_same = False

            for k in range(cols):
                if k != j and matrix[i][k] == current_val:
                    found_same = True
                    break

            if found_same:
                result.append(i)
                break

    return result
