a = {'a', 'b', 'c'} b = {'d', 'e', 'f'} I want to add above two set values. I need output like
c = {'a', 'b', 'c', 'd', 'e', 'f'} 4 Answers
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.
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) 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)) #this will print a sorted list Or simply print unsorted union of a and
print(c) #this will print set c If you wanted to subtract two sets, I tested this:
A={'A1','A2','A3'} B={'B1','B2'} C={'C1','C2'} D={'D1','D2','D3'} All_Staff=A|B|C|D All_Staff=sorted(All_Staff.difference(B)) print("All of the stuff are:",All_Staff) Result:
All of the stuff are: ['A1', 'A2', 'A3', 'C1', 'C2', 'D1', 'D2', 'D3']
