Почему Python говорит, что не может получить доступ к локальной переменной «min_distance», если она не связана со значен ⇐ Python

[Anonymous]

Я написал код, вычисляющий положения планет, однако по какой-то причине получаю ошибку 'невозможно получить доступ к локальной переменной 'min_distance', где она не связана со значением'
Я не знаю почему, min_distance уже было глобальным значением, так как в функцию Compute_position(min_distance) я уже включил min_distance и обновил его вне функции.
Я изменил функцию на Compute_position( min_distance) просто вычислить_position() и объявил min_distance глобальным, но это не сработало.
