recover the size in bytes only of epub files

[oles]

Good morning,

I use the formula below, but it shows me:
EPUB:1182150,KEPUB:701399

but I only want to have the epub and the size in bytes like this:
1182150


The current formula is:
{:'formats_sizes()'}

Do you have a tip? It seems to be python, but I didn't succeed with things proposed by chatgpt (lol) like:
{:'formats_sizes().get("EPUB")'}
{#formats.contains('EPUB') ? formats_sizes('EPUB'): ''}



THANKS

The template language documentation is at https://manual.calibre-ebook.com/template_lang.html. It isn't remotely python.

This Template Program Mode template does what I think you want.

{:'select(formats_sizes(), 'EPUB')'}

You might prefer this one that gives the size in kb or mb:

{:'human_readable(select(formats_sizes(), 'EPUB'))'}

Or perhaps this one that adds commas to the size:

{:'format_number(select(formats_sizes(), 'EPUB'), ',d')'}
