Function that allow a user to create a list

#create a function that allow a user to create a list

#function name: createList
#parameter: word
#returns the list

def createList(quitword):
    mylist = [] # create an empty list

    while True:
        #get the item from the user
        item = input('Please enter a list item: ')

        
        #when the user enters an item that is equal to quitword
        if (item == quitword)
        return mylist # return the list


        #check if the list already has that word
        duplicateword = False

        # figue out of the word is already in the list
        For myvar in mylist:
            if myvar == item:
                duplicaeword = True

        #...... loop through the list and compare each value

        if duplicateword == True: #duplicate is true
            print ('Duplicate word!')
        else:
            #add this item to the end of the list
            mylist.append(item)
