Example 1: |= operator python
>>> s1 = {"a", "b", "c"}
>>> s2 = {"d", "e", "f"}
>>>
>>> s1 | s2
{'a', 'b', 'c', 'd', 'e', 'f'}
>>> s1
{'a', 'b', 'c'}
>>>
>>> s1 |= s2
>>> s1
{'a', 'b', 'c', 'd', 'e', 'f'}
Example 2: python operators
OPERATOR DESCRIPTION SYNTAX FUNCTION IN-PLACE METHOD
> Greater than a > b gt(a, b) __gt__(self, other)
>= Greater or equal to a >= b ge(a, b) __ge__(self, other)
< Less than a < b lt(a, b) __lt__(self, other)
<= Less or equal to a <= b le(a, b) __le__(self, other)
== Equal to a == b eq(a, b) __eq__(self, other)
!= Not equal to a != b ne(a, b) __ne__(self, other)
OPERATOR DESCRIPTION SYNTAX FUNCTION IN-PLACE METHOD
+ Addition a + b add(a, b) __add__(self, other)
– Subtraction a - b sub(a, b) __sub__(self, other)
* Multiplication a * b mul(a, b) __mul__(self, other)
/ True Division a / b truediv(a, b) __truediv__(self, other)
// Floor Division a // b floordiv(a, b) __floordiv__(self, other)
% Modulo a % b mod(a, b) __mod__(self, other)
** Power a ** b pow(a, b) __pow__(self, other)
OPERATOR DESCRIPTION SYNTAX FUNCTION IN-PLACE METHOD
& Bitwise AND a & b and_(a, b) __and__(self, other)
| Bitwise OR a | b or_(a,b) __or__(self, other)
^ Bitwise XOR a ^ b xor(a, b) __xor__(self, other)
~ Bitwise NOT ~ a invert(a) __invert__(self)
