bool and int types in boolean contexts

Question

I have this code in a boolean context:

True and False or 2  

Output: 2

The type check for this expression resulted in int.

Next, I modified the code to:

True and False or True 

Output : True And the type check for this expression resulted in bool

• Why is the output in the 1st code 2?
• Shouldn't the expression evaluate to a boolean value ?
  If not so, Why?

Answer 1

All you need to know here is the definition of OR operand.Based on python documentation :

The expression x or y first evaluates x; if x is true, its value is returned; otherwise, y is evaluated and the resulting value is returned.

So since the precedence of or is lower than and your expression evaluated as following :

(True and False) or 2

Which is equal to following :

False or 2

Thus based on preceding documentation the result would be the value of right object which is 2.
