Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

It's a simple concept, but the code itself is pretty complex (to me, at least, since i dont understand some of it)

static matrix

#

my objective is for it to handle these types of inputs

#

Fe, FeCl, FeCl + H2O, H2O + H2O + Cl + Fe + etc....

#

H2O - H2O, FeCl - O2, etc.

#

simple addition subtraction and formulae

coral jackal
#

ill show each input

#

As you can see

#

it doesnt handle addition with whitespace

#

for H2O + Cl

#

AND for some reason

#

i think it interprets Cl+H2O as (Cl+H2) and then O

#

i have a feeling i positioned the validity check of the syntax in a very horrible place

#

organic compounds like this work just fine

#

but literally its such a simple issue that i cant get my head around

#

i just need the code to interpret

<whatever the hell> + <whatever the hell> as it is

#

just split them from the + symbol and add their masses

#

but it aint working

#

also i didnt add subtraction but im guessing if i can fix addition thatll be a simple copy paste

#

how did you come up with the regex for valid expressions?

coral jackal
#

lets say i didnt rlly come up with it

#

and i mightve used some assistance

#

(i dont remember any of my python knowledge from 2 years ago, and i cant bother studying again from the basics)

#

oh yeah also inputs like this work for some reason

#

H2O,Cl,H2O,F,Ag,Au etc

#

but i dont want it to be a comma

#

and i also dont want it to be a + with no whitespace, e.g. C+C

#

and i have a feeling a big part of the code is redundant and should be deleted to save space

#

no idea

#

ยฏ_(ใƒ„)_/ยฏ

#

was i not able to explain well

#

alr man .-.

tight bloom
#

idk how to help you with code you don't understand

#

i guess my advice would be to understand it first

#

you can use regex101.com to play arounod with your regex to see what it's doing

coral jackal
#

nah dont worry ill try to understand

#

i just want to publish this project and then work on more basic stuff

#

alright man
