Could the "embeddable package" ones also sort below the "installer" ones?

That way the first Windows thing people see in list is our Recommended one.

[hugovk]

Updated to put those matching file.name.startswith('Windows embeddable package') last:

Older ones (see right column) have a different filename structure, so it doesn't match them:

We could match something like 'embeddable' in file.name, but maybe we don't need to worry about the older ones?

[gpshead]

I wonder how many people download the windows help file (whatever that is). it could be sorted lower, probably below the installers before embedded.

regardless, this PR is good. lets ship it and iterate further later.

[hugovk]

Updated with an explicit preferred sort order for Windows files, how does this look?

[gpshead]

nice!

@ewdurbin Please merge this.

Are these strings generated by code elsewhere in the codebase or manually input by Release Managers?

If it is manual input, this feels brittle and likely to cause confusion.

[ewdurbin]

They appear to be strings stored on the ReleaseFile model via the NameSlugModel mixin. I'm pretty iffy on handling this this way honestly.

@Yh1gs for RM input

[Yhg1s]

Yes, they're freeform strings, set by the script adding the ReleaseFile objects: https://github.com/python/release-tools/blob/master/add-to-pydotorg.py#L90.

[hugovk]

Before checking for the exact strings, I had something that checked for substrings like "(64-bit)", "(32-bit)" and "Windows embeddable package", see the old version at: dadd924 (#2311)

Would you prefer something like that? Or some other approach?

[merwok]

IMHO having the strings is fine, if comments were added to reference this file from the other and vice-versa

I'm willing to help with whatever needs doing here, just let me know.
