How do you convert int to boolean in Python?

Why do we have method that returns bool / int?
Perhaps this is a method someone before you was using to guarantee that baz was being passed by reference without understanding how object parameters actually work in C#. Sometimes this pattern is useful when you, the caller, aren’t supposed to care whether the returned type is a reference or value type.
When to use a void instead of a Boolean?
So in these cases, it is perfectly fine for a method to return nothing (i.e. void) instead of a boolean status flag or an integer status code. (Of course one should document what exceptions the method may throw and when.)
Which is declared as an int in the for loop?
As you can see, your method is returning i which is declared as an int in the for loop, so the return type of your method has to be the same as the type of the variable it returns. Thanks for contributing an answer to Stack Overflow!
Can you return I as a Boolean in Java?
You can cast i as a boolean, or change return i; to return i != 0;, which will be true for all non-zero values of i, and false if i == 0. As a side note, I really see no reason to wrap a return in a for loop.
