Logical operator or
expression or expression
The logical operator or returns false if and only if both expressions are false, otherwise returns true . Now, in Python (and in many languages) it is compared in the following way:
false = 0
true = 1
then if you put any number greater than 0 the interpreter will consider it as True . If you use the logical operator or for anything that is not Boolean unexpected things start to happen, for example when you put the sentence
2 or 8
2
in this case it returns the first value "True", for example:
False or 8
8
As a recommendation, use the logical operator or only in Boolean operations
Operator "or" bit by bit | or operator.or_(2,8) (bitwise)
number | number
the bitwise operator is designed to work normally with numbers, and basically compares bitwise numbers, as an example
2 es 0010
8 es 1000
then the bitwise comparison with the logic "or" (0 with 0 is 0, 1 with 0 is 1, 0 with 1 is 1 and 1 with 1 is 1) gives us the following
1010
that in binary is equivalent to 10. As you can see, in bitwise operations the order of the operands is irrelevant, that is why:
2 | 8 = 8 | 2 = 10
