    What's the problem?

    @spl0 they could have just done

    return foo();

    @c3ypt1c return bool(foo())
    Please:)

    @c3ypt1c oh my god! That semicolon... Lol 😨

    @c3ypt1c no it's not the same. We don't knoe that foo() returns Boolean.

    If the if statement can evaluate foo() as a Boolean 9 times out of 10 you can assume that it is one.

    @spl0 there is the only one way to do that. See my comment...

    @Romulus10 ummm, depends on the language...

    The syntax here is pythonic.

    @Romulus10 well in python... for example, you could return 1 or 0. Thats not a boolean, but 'if' would still treat it as one....

    In that case, this code could still be avoided. foo() could return directly to the target and would evaluate the same as if this code returned true or not.

    Wish your code on my review guys...:)

    @Romulus10 Yes but its an int. Just because if makes something of it, doesnt mean you can assume its a boolean!
  • 1
    8y
    Yeah, that assumption could probably end up not being the best practice. In most cases, though, I would probably leave this bit out.

    From where I'm looking at it, leaving out the conditional will make the common case faster.

    @Romulus10 I think lig's return bool(foo()) is probably the best unless we know foo() returns boolean, in which case just return foo()?

    I wonder why (out of context of course) we couldn't skip the return statement and just call foo() from where we need it returned to.

    8y
    @Romulus10 Because (in theory) we dont know whats before this code in the same function....

    Yeah, that's why I said out of context. The fact that there are no arguments to foo() makes me think it should be safe but there's always the possibility.

    @lig1 you can use semicolons in python... ;3 I do it out of habit...

    @c3ypt1c moreover they is always a semicolon at the end of each line in Python. Even if you don't see it...
