When a look at ('Parker' and 'May' and '2001') i can't help it but 
interpret it as:

Return True if  'Parker' is not an empty string AND 'May' is not an 
empty string AND'2001'  is not an empty string.

Why on eart doesn't work this way?

I can understand that the value it results to '2000' is a truthy value, 
although i was expecting it to result in True if all parts of 
expressions are true.

i just don't understand why it returns back the last value instead.

Why does it return th first object back
isn't it like saying False and True and resulting in False?

Please put it in else word how Python unerstand that.

Same here? The 2nd part of the expression never is been calculated 
because the 1st is False?

Same here? The 2nd part of the expression never is been calculated 
because the 1st is False?
