Is there a way to format the default integer value or any value entered using a comma as a thousand-separator when using a st.number_input() widget?

Hi!
I’ve read several posts and tried different things to get this to work, but so far I am not getting the desired results. I am using a st.number_input() widget. The default value is an integer usally large, in the hundreds of thousands if not millions. The ideal situation would be to format the default value appearing when rendering the widget with the comma to separate thousands and make it easier to read, i.e. if the default value is 1000000, then when the widget is rendered it should indicate 1,000,000. I have tried different arguments for the format parameter with no luck. I do not want to convert this to text and then back to a number because it seems like it would require a “Submit” button, which I do not want to incorporate (This last statement based on an error I got when I was trying different options).

Any idea how to incorporate the comma/thousand separator when displaying the default integer in a st.number_input() widget?

Below how it currently renders on my app:

According to the docs

Formatting is handled by sprintf.js.

which doesn’t seem to support thousand separators.

Yeah, I looked into that, not sure if there is some kind of workaround… Thank you for the reply

Done… looks like this is going to take a while…
