Solution Exercise 204: python program that determines the complement of a subset in given set

Exercise 204

Write a Python program as function which takes as parameters two sets E and F, such that E included in F and returns the complement of F in E. Example if

E = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'}

and

F = { 'c', 'd', 'e',  'h'}

The function returns:

{'a', 'b', 'f', 'g'}

Solution

def complemntSets(E , F):
    
    # initializing the complment of set F
    Complement_F = set({})
    
    for x in E:
        if x not in F:
            Complement_F.add(x)
            
    return Complement_F

# Testing algorithm
E = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'} 
F = { 'c', 'd', 'e',  'h'}
print("Complement_F = " , complemntSets(E , F))
# display: Complement_F =  {'f', 'g', 'a', 'b'}
