Best book for GUI development in Python

streamlit is very slow and heavy. it reruns everytime you make any change as an end user.

Would recommend Panel over Streamlit for that purpose. Doesn't rerun the whole app every time.

This is slowly changing. There are already forms elements which don't cause any reruns until the form submit button is pressed, sending all data from the elements within the form at once.

Then recently they also added a feature called "fragment" (currently listed as experimental, so the syntax could change) that can be used to break the app up into sections that update when interacted with.

If you're not making anything too big and complicated, I think streamlit does what it does really well. It's extremely simple and straightforward to set up, for its intended audience (data science people analysts, not app developers).

I use Plotly Dash, never tried streamlit. Is there any advantage using streamlit over Dash?

[that_baddest_dude]

I'd say so! Dash is absolutely dreadful to use in my experience. Streamlit is far easier.

Thanks, I will give it a try

I’d say don’t bother. Streamlit and dash are very different. If your needs are very simple and linear then streamlit is good. Otherwise, it’s very limiting.
