You can use the | operator to join two sets in Python. This combines the elements from both sets into a single set. By using this operator, you can also join multiple sets at a time. This would return a new set that contains all of the elements frommyset1andmyset2, without any du...
after concatenating the lists using a + operator, the resultant list is passed to the in-built set() method. As Python sets do not have any duplicate elements, this removes all the duplicates from the concatenated list. As we require a list, this set is...
join(lst[1:]) print(joined) # Bob + Liz # Join except last element joined = ' + '.join(lst[:-1]) print(joined) # Alice + Bob This way, you can join all list elements, except the first or last elements. Python Join List Remove Duplicates Problem: Given two lists [1, 2, 2,...
