(45 or False)
Above statement returns 45 as the out put in python, rather than returning True or False or (0 or 1).
But in php It returns 1 as the output. what is the rationality behind this?

1`or` returns the value that determines the outcome of the expression. That's just how it is defined. Are you asking why the language was designed this way? – Felix Kling Nov 09 '16 at 03:40

@dulajsanjaya, in php it also gives 45: http://sandbox.onlinephpfunctions.com/code/b5d0e1b964f6bdcd3983ba47dc67b9eed60915c5 – Dekel Nov 09 '16 at 03:44

@Dekel But if you add parenthesis like this $t = (45 or False); ,It returns bool(true) – dulaj sanjaya Nov 09 '16 at 03:53

@Dekel: that's not quite right. `or` is weird because it has a different precedence. The code is executed as `($t = 42) or false`. – Felix Kling Nov 09 '16 at 04:01

correct, in php the `or` operator gives you the result of the evaluation (true if one of the sides are not false, false otherwise). – Dekel Nov 09 '16 at 04:06
