How do I add two sets?

Question

a = {\'a\', \'b\', \'c\'} 
b = {\'d\', \'e\', \'f\'}

I want to add above two set values. I need output like

c = {\'a\', \'b\', \'c\',         


        

Answer 1

You can use the result of union() of a and b in c. Note: sorted() is used to print sorted output

    a = {'a','b','c'} 
    b = {'d','e','f'}
    c=a.union(b)
    print(sorted(c))

Or simply print sorted union of a and b

    a = {'a','b','c'} 
    b = {'d','e','f'}
    print(sorted(a.union(b)))

Answer 2

All you have to do to combine them is

c = a | b

Sets are unordered sequences of unique values. a | b or a.union(b) is the union of the two sets (a new set with all values found in either set). This is a class of operation called a "set operation", which Python sets provide convenient tools for.

Answer 3

You can use .update() to combine set b into set a. Try this:

a = {'a', 'b', 'c'}
b = {'d', 'e', 'f'}
a.update(b)
print(a)

To create a new set, c you first need to .copy() the first set:

c = a.copy()
c.update(b)
print(c)
