The pattern you describe matches nigh-exactly the functionality of
the :g command

:g/^\s*def\>/ACTION

You don't mention *what* you want to do for each of these lines, but
the ex-mode :g command gives you lots of power. From each of those
matching lines, you can define a range relative to that line and
perform any command you want over that range. It could be as simple
as "append a comment after every function definition":

:g/^\s*def\>/s/$/ # my comment here

or adding a Python docstring underneath it:

:g/^\s*def\>/put='"Docstring here"'

or indent the following line through the next blank line:

:g/^\s*def\>/sil! +,/^\s*$/->

That's the implicit way of writing the clearer

:g/^\s*def\>/sil! .+1,/^\s*$/-1>

It (and its counterpart ":v") is one of the most powerful vim
commands and I use it nigh-daily.
