Full Discussion: Feed python with read line in shell

I have no idea what you are trying to do.

You do three things every time you read a line from a file:
  1. run a python script that reads no input,
  2. sleep for two seconds, and
  3. echo the contents of a variable that has never been defined to the standard output of your script.
In a more normal sequence of operations, one might expect to see something more like:
Code:
python test.py < keywords

or, if the data in keywords needs to be massaged in some way before being passed on to python:
Code:
while read -r line
do	# do whatever needs to be done to $line before passing it on to python
	... ... ...
	# pass on the modified line to python
	printf '%s\n' "$line"
done < keywords | python test.py

renpy

renpy(6)							       Games								  renpy(6)

NAME

       renpy - engine for creating visual novels

SYNOPSIS

       renpy [path to the script directory]

DESCRIPTION

       Ren'Py  is  a programming language and runtime, intended to ease the creation of visual-novel type games. It contains features that make it
       easy to display thoughts, dialogue, and menus; to display images to the user; to write game logic; and to support the saving and loading of
       games.

       Ren'Py tries to be like an executable script, allowing you to get a working game without much more effort than is required to type the game
       script into the computer.

       Ren'Py is implemented on top of python, and that python heritage shows through in many places. Many Ren'Py statements allow python  expres-
       sions  to  be  used, and there are also Ren'Py statements that allow for the execution of arbitrary python code. Many of the less-used fea-
       tures of Ren'Py are exposed to the user by way of python. By only requiring use of the simplest features of python, it's hoped that  Ren'Py
       will be usable by all game authors.

USAGE

       If  you	run  the  program  without  any  arguments, zou will get an interactive launcher from where you can select, run and work different
       projects.

       For running a script, you need to give the full path to the directory that contains the game you want to play.

       For example: renpy /usr/share/games/renpy/demo/

       To learn how to use the game interface, you should install and play renpy-demo.

FILES

       The game data for each user is stored at ~/.renpy/ directory.

       The scripts can be installed in the system bz placing them under /usr/share/games/renpy/ , but you can  run  any  script  in  an  arbitrarz
       directory just by telling the path as the parameter to the game.
