​Almost certainly.  I started using CamelCase in the mid-'80s and it seems
very natural to me, since we still use it for (as you mention) GUI packages
derived from C extension modules with that convention.  On the other hand,
I've also written a lot of snake_form identifiers in non-GUI Python, so
that seems fairly natural to me, too.​
