I've modified answer from MrBones and created custom function with keybinding:

; create empty __init__.py at the place
(defun create-empty-init-py()
  (interactive)
  (shell-command "touch __init__.py")
)
(global-set-key (kbd "C-c p i") 'create-empty-init-py)

This is very useful to not spend time on recurring action of creating init.py everywhere in new Python project folder.
