exec() won't work (don't work like i think)

[daring forge]

Hi, I have part of my code that does this (see ss)

function is for example equal to y=x. My goal of this piece of code is therefore to give the value of the left member (here x) to y from a variable of type string using exec().

The problem is that according to my command editor, exec() in my code "does nothing" (it does not give a new value to y
anyone know what to do?

function()? why are u using exec

exec (as far as i know) is used to run functions through a 'string format'. unless you're using user input, why exec?

[daring forge]

because function is a string object

[viscid badger]

once again

why

[daring forge]

function is type by the user (for a well particular reason) and verify by the program that its well a mathematic function (and not a try of code insertion)

[viscid badger]

is y a global variable?

[daring forge]

i never declared y as a global

i tried on my cmd and it worked

[daring forge]

but ofc it won't work on my program

[daring forge]

should i try with y on global ?

here's the program with x and y global (this also don't work)

[viscid badger]

using exec will not update the local variable of y, just the y variable within that exec function

[daring forge]

you mean x

cuz i defined y on the exec()

(function = "y=x")

[viscid badger]

k hold on, ive never used exec so ill try

[daring forge]

k

thx

[daring forge]

i already tried this

and x or y is not global here (i think)

but it work

whytf

[viscid badger]

so your setup for function is

def function(self):
    return "y = x"

for function?

[daring forge]

hmm its not writed like this on my code but i think that its the same

on my code...

function = user_input

(user_input is then a string)

[viscid badger]

yeah you can't cross-reference variables like this

the function call will not change the y variable of the function where you call it from

so you'd have to make it a global one in the call

aka

exec(function, globals())

[daring forge]

and i put x and y in globals ?

like this ?

exec(function, globals(x, y))

[viscid badger]

no

you just do what i sent

and it will make the provided variable within function as global

[daring forge]

this ?

[viscid badger]

exec(function, globals())

this.

[daring forge]

k

i'll try

[viscid badger]

you still have to make x global if you want to reference it

ie, "y = x"

[daring forge]

i think that's worrking

thank you 🥹
