[Python] Read write on local drive through Streamlit application as executable (built using...

new to streamlit and have no experience with npm. I have created streamlit app and packaged it as an executable .exe following a tutorial https://youtu.be/3wZ7GRbr91g?si=8FLBt3PsAxvEEzjo . streamlit graphs/ functions (buttons, filters etc.) is working fine using package.json I created as follow,


{
"name": "95L_schedule",
"version": "0.4.0",
"main": "./build/electron/main.js",
"scripts": {
"dump": "dump-stlite-desktop-artifacts",
"serve": "cross-env NODE_ENV=production electron .",
"servewindows": "electron .",
"pack": "electron-builder --dir",
"dist": "electron-builder",
"postinstall": "electron-builder install-app-deps"
},
"build": {
"files": ["build/**/*"],
"directories": {
"buildResources": "assets"
},
"win": {
"target": "portable"
}
},
"devDependencies": {
"@stlite/desktop": "^0.76.0",
"cross-env": "^7.0.3",
"electron": "^33.0.1",
"electron-builder": "^25.1.8"
},
"stlite": {
"desktop": {
"files": ["streamlit_app/app.py"],
"entrypoint": "streamlit_app/app.py",
"dependencies": ["numpy", "pandas", "plotly-express"]
}
}
}

And then in the windows command prompt


npm install
npm run dump numpy pandas matplotlib
npm run dist

through my streamlit code, I want to be able to write files (save matplotlib figures) on the local drive where this executable is running.

I tried accessing the current working directory with something like below but it does not work, I am assuming executable is running in some sort of npm shell and not on windows itself.


with st.form(key='create_prints'):
submit_button = st.form_submit_button(label='create printable files')

if submit_button:
base_path = os.getcwd() + "/" + assign['start_timestamp'].min().strftime('%Y%m%d') + "/"
os.makedirs(base_path + "machines/", exist_ok=True)

How should I go about it? thank you!
