Destructible Lemon

@ais523 why is this needed and I don't understand

ais523

@DestructibleLemon I'm trying to map the space of what's possible in polyglots

identifier( is a very promising start in a lot of languages, but I've hit something of a wall in Python

however, I don't know the language very well, so maybe there's some trick I'm missing

Destructible Lemon

how arbitrary?

# is nice

ais523

# isn't an identifier

Destructible Lemon

what is an identifier?

ais523

1:08 AM

identifiers are made out of letters/digits/underscores and start with a letter

Destructible Lemon

again, how arbitrary?

because unlike other langs, variables don't have undefined value or undefined behaviour before assigned. they just error

ais523

I can't control it to something that has specific meaning to Python, and apart from that, I'd expect all of them to work equally well

(or to not work equally well)

Destructible Lemon

except for preassigned variables like builtin functions

ais523

the problem is that Python appears to be evaluating the function before its arguments

(if you do it the other way round you can exit in the middle of the argument list so that the function never gets evaluated)

Destructible Lemon

yeah, any code you could do that with would have to come before that code anyway

ais523

1:10 AM

hmm… is there a way to run code at parse time in Python?

user165474

exec

ais523

that's the other way round, that lets you parse at runtime

Destructible Lemon

no idea

ais523

even then, I think Python probably stops parsing as soon as it sees an undefined variable
