I didn't understand operator precedence example in python. Can someone explain?

Question

operator precedence example in python

Answer 1

I think that you referring to table precedence. Imagine this expression:

-2**4

How python resolve it? Raise to 4th power -2 or negate the result of 2 power 4? The answer is on that table and in this case interpreter raise 2 to 4 then negate the result because exponentation operator (**) has higher precendence with respect to negation operator (-). try to execute

print(-2**4)

and see

Answer 2

False == False or True
True
>>> False == (False or True)
False
>>> (False == False) or True
True
Can u please explain this example?

Answer 3

Well, comparison operators have HIGHER precendence on logical operators (like or) and grouping operator have higher precedence an all then:

1) False == False or True => True or True => True

2) False == (False or True) => False == True => False

3) (False == False) or True => True or True => True
