The union method
The union method returns a set obtained by combining the elements of the sets specified in the parameter.
Syntax
pythonset.union(sets we want to unite)
Example
Let's apply the union method to get the common elements of two sets:
pythonst1 = {'a', 'b', 'c'}
st2 = {'1', '2', '3'}
res = st1.union(st2)
print(res)
Result of code execution:
python{'c', '2', 'b', '1', 'a', '3'}
Example
The union method also has a short form:
pythonst1 = {'a', 'b', 'c'}
st2 = {'1', '2', '3'}
res = st1 | st2
print(res)
Result of code execution:
python{'a', '1', 'b', '3', '2', 'c'}
