Нужно найти другие решения задачи.

возможные иные решения в етих задачах?

Код вставляйте с помощью ... -> код -> python.

Да. Вот, например, вариант решения первой задачи:

class Concert:
    max_visitors_num = 0

    def __init__(self):
        self._visitors_count = 0

    @property
    def visitors_count(self):
        return self._visitors_count

    @visitors_count.setter
    def visitors_count(self, value):
        if value <= self.max_visitors_num:
            self._visitors_count = value
        else:
            self._visitors_count = self.max_visitors_num


Concert.max_visitors_num = 50
concert = Concert()
concert.visitors_count = 1000
print(concert.visitors_count)  # 50
