I do know how we pass one variable from python to c shell script but I am having trouble in passing multiple python variable to c shell script. Please let me know how do we achieve this. Here is the link where I came to know to pass single variable from python to c shell script.

How to pass the Python variable to c shell script

The answer you're using as a starting point is... really quite awful; shlex.split() rather explicitly shouldn't be used in this case. – Charles Duffy Jan 30 '15 at 14:41
    
That said -- what have you tried so far, and how did it fail? – Charles Duffy Jan 30 '15 at 14:44
    
None of this is specific to csh, by the way -- the environment and argument vector are both universal concepts; passing content through them is the same no matter what language the receiving program is written in. – Charles Duffy Jan 30 '15 at 14:45

Pass each argument as a separate argv entry:

first_var='hello'
second_var='world'
subprocess.Popen(['program_name', first_var, second_var], shell=False)

By contrast, if you want to pass multiple variables through the environment, they should both be keys in the env dictionary:

subprocess.Popen(['program_name'], env={
  'first_var': first_var,
  'second_var': second_var,
})

Thanks Charles, This is exactly what I was looking for as the previous solution that I referred in the question was bit confusing. – nprak Jan 30 '15 at 18:31
