[linux] How to check if a file is empty in Bash?

I came here looking for how to delete empty __init__.py files as they are implicit in Python 3.3+ and ended up using:

find -depth '(' -type f  -name __init__.py ')' -print0 |
  while IFS= read -d '' -r file; do if [[ ! -s $file ]]; then rm $file; fi; done

Also (at least in zsh) using $path as the variable also breaks your $PATH env and so it'll break your open shell. Anyway, thought I'd share!
