# to remmove items from a set you use discard() or remove() your best bet is to use .discard() unless you are very sure that the element in question is really in the set.

#******* using the .pop() method
print(a_set)
# a_set.pop()

# ****this strategy shows you which item was poped out
# fim = a_set.pop()
# print(a_set, fim)

# **** this clears out all the elements of the set.
