set in python

1let mySet = new Set()
2
3mySet.add(1)           // Set [ 1 ]
4mySet.add(5)           // Set [ 1, 5 ]
5mySet.add(5)           // Set [ 1, 5 ]
6mySet.add('some text') // Set [ 1, 5, 'some text' ]
7let o = {a: 1, b: 2}
8mySet.add(o)
9
10mySet.add({a: 1, b: 2})   // o is referencing a different object, so this is okay
11
12mySet.has(1)              // true
13mySet.has(3)              // false, since 3 has not been added to the set
14mySet.has(5)              // true
15mySet.has(Math.sqrt(25))  // true
16mySet.has('Some Text'.toLowerCase()) // true
17mySet.has(o)       // true
18
19mySet.size         // 5
20
21mySet.delete(5)    // removes 5 from the set
22mySet.has(5)       // false, 5 has been removed
23
24mySet.size         // 4, since we just removed one value
25
26console.log(mySet)
27// logs Set(4) [ 1, "some text", {…}, {…} ] in Firefox
28// logs Set(4) { 1, "some text", {…}, {…} } in Chrome

1a = int(input())
2b = int(input())
3s = a+b
4print(S)

1The simplest way to create set is:
21. from list
3code:
4	s = [1,2,3]
5	set = set(s)
6	print(set)
7
82. s,add() method
9code:
10	set.add(1)
11	set.add(2)
12	set.remove(2)
13	print(set)  // 1
14
153. Set conatins unique elements

1self.val2 = kwargs.get('val2',"default value")

1A_Set = {1, 2, "hi", "test"}
2
3for i in A_Set: #Loops through the set. You only get the value not the index
4  print(i) #Prints the current value
