Comma(,) has associativity from left to right.
In line 7, i.e, if(a,b,x,y), only the last variable will be checked as a test condition, rest all other will be ignored.
Now, the if part becomes something like if(y), or if(10), which is True, as 10 is not equal to zero. Hence, the if part gets executed, and we get output as hello.
