Look into 're' module.  Essentially, split using '...', but return the
separator as well.  Then, remove empty items.  In Bash shell, you would
do
    a="Hello World"
    set -- "${a|?...}"		# extract '...' separators
    pp_collapse			# remove null items
    printf '{%s}\n' "${@}"

Translating to Python is left as homework.
