I'm asking just because I'm curious.
Are you looking for somebody that can make you a flask or django web app? (or something similar) I'm assuming since you mentioned that you needed python code and some UI with html and css that you have something a stack similar to those but because you mentioned a "python terminal" make it sound odd to me, I think my question might help make it more clear to potential devs wanting to apply.
Whatever you can do to make it work. I am currently using visual studio to house the python code which has a terminal. I haven't done any UI so if you wanna use a web app then thats fine.
