the set add method inserts one item,
the set update method is an in-place union, and
remove method deletes an item by value.

y = set('bdxyz') 

z = x.intersection(y) # Same as x & y 
print( set(['b', 'd']) ) 
z.add('TEST')                  # Insert one item 
print( z ) 

z.update(set(['X', 'Y']))      # Merge: in-place union 
print( z ) 
z.remove('b')                  # Delete one item 
print( z )
