Hey guys I'm having some trouble with a homework question from Zelles python. I have to make a Set class then test a variety of methods. However my teacher wants us to just use lists and not actually sets. I'm getting an error for the setElements method, it keeps saying I need two arguments but only one given.

class Set:

    def setElements (self,elements):
        self.set1=list(elements)    

    def addElement(self,x):
        if not x in self.set1:    
            self.set1.append(x)

    def member(self,x):
        x in self.set1

    def deleteElement(self,x):
        self.set1.remove(x)
        
    def intersection(self,set2):
        self.set1.intersection(set2)

    def union (self,set2):
        set1.union(set2)
 
    def subtract(self,set2):

        set3 = Set([])
        for i in self.elements:
            if set2.member(i) == False:
                set3.addElement(i)
        return set3


def main():
    elements= eval(input("Enter a list: "))
    set1=Set.setElements(elements)

    x=eval(input("Enter a number to add to the set: "))
    set1.addElement(x)

    x=eval(input("Enter a number to see if it is in the set: "))
    print(set1.member(x))

    x=eval(input("Enter a number to delete from the set : "))
    print(set1)

    elements2= list.eval(input("Enter a list: "))
    set2=Set.setElements(elements2)

    print(intersection(set2))
    print(union(set2))
    print(subtract(set2))

main()
