Can someone explain me the operator precedence?

Question

why this happen?

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

Answer 1

1st case: it's true that false equals false so the subsequent or statement is met and the result is true as the equation looks like True or True
2nd case the or statement is met because one of the conditions is true. the final result is false as the equation looks like False==True
3rd case is equivalent to the 1st case and after checking that is true that false equals false, the or statement is met as the final equation looks like True or True.

As a rule of thumb solve first the operations enclosed in brackets and later on, the rest always taking care of operators precedence (* and / come before + and -)
