    I found this variant:

    def get_kb(number_of_buttons):
    markup = InlineKeyboardMarkup()
    lines = int(number_of_buttons/3)+1
    last_lines = (number_of_buttons % 3)
    for i in range(1, lines):
        markup.add(InlineKeyboardButton('button ' + str(i ** i), callback_data='button_' + str(i ** i)),
                   InlineKeyboardButton('button ' + str(i ** i + 1), callback_data='button_' + str(i ** i + 1)),
                   InlineKeyboardButton('button ' + str(i ** i + 2), callback_data='button ' + str(i ** i + 2)))
    if last_lines == 0:
        markup.add(InlineKeyboardButton('others', callback_data='others'))
    elif last_lines == 1:
        markup.add(InlineKeyboardButton('button ' + str(q), callback_data='button ' + str(q)),
                   InlineKeyboardButton('others', callback_data='others'))
    else:
        markup.add(InlineKeyboardButton('button ' + str(q-1), callback_data='button ' + str(q-1)),
                   InlineKeyboardButton('button ' + str(q), callback_data='button ' + str(q)),
                   InlineKeyboardButton('others', callback_data='others'))

    But I think that isn't the best variant

    Based on your own answer and since you mentioned aiogram in your comment, there’s already a feature implemented inside the library for your use case:

    # number_of_buttons_in_row would be 3 in your case
def get_kb(number_of_buttons, number_of_buttons_in_row):
    markup = InlineKeyboardMarkup()    
    markup.row_width = number_of_buttons_in_row     # key part is here

    for i in range(1, number_of_buttons):
        markup.add(InlineKeyboardButton('button ' + str(i ** i), callback_data='button_' + str(i ** i)),
                   InlineKeyboardButton('button ' + str(i ** i + 1), callback_data='button_' + str(i ** i + 1)),
                   InlineKeyboardButton('button ' + str(i ** i + 2), callback_data='button ' + str(i ** i + 2)))

    markup.add(InlineKeyboardButton('others', callback_data='others'))
    markup.add(InlineKeyboardButton('button ' + str(q), callback_data='button ' + str(q)),
               InlineKeyboardButton('others', callback_data='others'))

    markup.add(InlineKeyboardButton('button ' + str(q-1), callback_data='button ' + str(q-1)),
               InlineKeyboardButton('button ' + str(q), callback_data='button ' + str(q)),
               InlineKeyboardButton('others', callback_data='others'))
    return markup

    As you can see there’s a field called row_width inside markup, that’s used to slice the buttons into the given width and place them in several lines
