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

lp-shell

lp-shell(1)						      General Commands Manual						       lp-shell(1)

NAME

       lp-shell - Open an interactive launchpadlib shell.

SYNOPSIS

       lp-shell [-a] [-cPROGRAM] [--python] [--ipython] [service] [LP API version]

DESCRIPTION

       lp-shell opens an interactive Python shell with a launchpadlib.Launchpad object "lp" which is ready for use.

       It  authenticates against Launchpad with the consumer name "udt-lp-shell". When using lp-shell with the -a option it will use the anonymous
       login from launchpadlib.Launchpad.

       By default lp-shell connects to the "production" Launchpad service using the "1.0" LP API version.

       If you want to connect to another Launchpad service, call lp-shell with the service name as the second argument. lp-shell supports all ser-
       vices known by launchpadlib Python module.  Currently known are (list can be incomplete or outdated): "production", "staging", "dogfood".

       A  different  LP  API version can be selected by passing the API version to use as the third argument. Current supported are: "beta", "1.0"
       and "devel".

OPTIONS

       -a     Login anonymously into Launchpad.

       -c PROGRAM
	      Don't enter a shell but only run the specified Python program and exit.

       --ipython
	      Use an ipython shell if available (default).

       --python
	      Use a regular python shell.
