python math operators

# Below follow the math operators that can be used in python
# ** Exponent	
2 ** 3 # Output: 8
# % Modulus/Remaider	
22 % 8 # Output: 6
# // Integer division	
22 // 8 # Output: 2
# / Division	
22 / 8 # Output: 2.75
# * Multiplication	
3 * 3 # Output: 9
# - Subtraction	
5 - 2 # Output: 3
# + Addition	
2 + 2 # Output: 4

python exponent operator

#python exponent operator
num = 2
new_num = num**2
#answer would be 4

|= operator python

>>> s1 = {"a", "b", "c"}
>>> s2 = {"d", "e", "f"}

>>> # OR, | 
>>> s1 | s2
{'a', 'b', 'c', 'd', 'e', 'f'}
>>> s1                                                     # `s1` is unchanged
{'a', 'b', 'c'}

>>> # In-place OR, |=
>>> s1 |= s2
>>> s1                                                     # `s1` is reassigned
