company = ['julia', 'erick', 'dillon']
my_tuple = tuple(company)
my_tuple
company[1]
my_tuple[1]
my_tuple[1] = 'eric'

tuples are immutable means that they cannot be changed or edited but in lists we can change data inside that list but how, by changing text or by changing position can some tell??

This video does not explain when to use Tuples or Lists, hence nobody will understand the difference.
