Call a Python Script from parallel shell scripts at the same time

Question

I have a question about the Python Interpreter. How does is treat the same script running 100 times, for example with different sys.argv entries? Does it create a different memory space for each script or something different?

System is Linux , CentOS 6.5. Is there any operational limit that can be observed and tuned?

I don't think Python will be the thing that limits you, but rather the OS (I'm thinking of ulimit and such) — ThinkChaos

I'm not sure what question you're asking here. Are you asking about how a python script can be called from multiple shell scripts concurrently (only the OS limits you I believe) or what happens when there are different arguments provided to a script? Could you clarify your question? Thank you. — wei2912

What happens when you call same python script multiple times with different sys.argv elements. For example assume that you run this script in a for loop from shell like bellow " for i in cat file do; src_python.py $i &; done " Just a random example for you to understand my question better. — Suner Evren

You won't have any problem with what you're trying to do. You can call the same script in parallel a lot of times, with different input arguments. (sys.argv entries). For each run, a new memory space will be allocated.
