I have a Perl script I want to embed into Python. Whenever I run Python the Perl code also should execute. Both codes are in same file. I am running from HPSA so there is no filename associated with code run.
Something like this?
from subprocess import call as sp_call
perlscript = """
use strict;
use warnings;
print "EHLO world\n";
"""
exitcode = sp_call(['perl', '-e', perlscript], shell=False)
If you need to capture the output from the Perl script etc, look at subprocess.Popen and friends.

I am creating a simple game that will have the character die a lot, and as a consequence will end the game. how can i make it to have something like pressing the space bar restarts the file or something along those lines? It's a very simple file, so i am just looking for a simple solution.
You could wrap your script in a
while True:
...
block, or with a bash script:
while true ; do
yourpythonscript.py

in my understanding, source in R is import and execute the code from source code. does Python has the equivalent function to import and execute.
Yes, you can import code/modules/etc using import in python. Here are some resources to get you started:

(If you know what you're doing, you may actually be looking for exec(open('filename').read()))

How i can run codes ( for e.g print('hello, world') ) when user in raw_input("Enter your value")?
I just want run some codes when user writing input from raw_input function.
For e.g when you are typing your message in chat room, you can see messages of other users also.
raw_input is blocking. You would need to use multiple threads or processes to make that work, and any print-like output would clobber what you were writing on the same line. If you wanted to make a chatroom-like experience, I wouldn't recommend it. You could try curses if you wanted to stay in terminal-land.

Why has os.linesep() been used here in my code?
def GetInstruction():
print(os.linesep)#<--------???
Instruction = input("> ").lower()
return Instruction
I don't know why you're using it, but from the docs:
The string used to separate (or, rather, terminate) lines on the current platform. This may be a single character, such as '\n' for POSIX, or multiple characters, for example, '\r\n' for Windows.
Basically represents the current line separator default for your current environment or platform.

I want to write a python code to run the job of the following Shell script for me:
for run in {1..100}
do
/home/Example.R
done
The shell script is basically running an R script for 100 times. Since I am new to python can somebody help me to write this code in python?
You could use subprocess.call to make an external command:
from subprocess import call
for i in xrange(100):
call(["/home/Example.R"])
You can use python's commands module to execute external commands and capture their output.
The module has a function commands.getstatusoutput(cmd), where cmd is the command you are looking to run, as a string.
Something like this could do the trick:
import commands
for x in xrange(100):
commands.getstatusoutput("/home/Example.R")
Each iteration of the for loop, the commands.getstatusoutput() function will even return a tuple (status, output), where status is the status after executing the program, and output being anything that the command would have written to stdout.
Hope that helps.
