But why?
that expression should return True since all stings are not empty.
It returns a value that counts as true in a conditional statement or
expression:
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.
Zeroes and empty things tend to count as false in Python, other values
as true. The values are tested as is, not coerced to a boolean first,
so the value that decides the value of the whole expression is the
value of the whole expression.
'' and whatever
''
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.
False and whatever
False
Same here? The 2nd part of the expression never is been calculated
because the 1st is False?
0 and whatever
0
Same here? The 2nd part of the expression never is been calculated
because the 1st is False?
1 and whatever
