На двата коментирани реда във функцията cell_at ми даваше грешка "Spaces around operators * no spaces around [] on line 65 * no spaces around [] on line 70", която не можах да разбера точно как да се справя с нея затова ги коментирах. Ако може да ми кажете какъв е бил проблема и как се решава. Благодаря!

@Емилия, извинявам се, че сме пропуснали да ти отговорим на този коментар.

Правилният запис на въпросните редове е следният:

# Bad - your version
@sheet.[](get_row(index[0]), index[1]) if index.length == 2

# Good - conventional usage
@sheet[get_row(index[0]), index[1])] if index.length == 2
