Just access the text using sys.argv like before. It's just another
element in the list; there's nothing special about it. You just need
to change the indices accordingly:

from sys import argv
text = argv[1]
filepath = argv[2]
# alternatively:
# text, filepath = argv[1:]
print("Your text input was:")
print(text)
print("The file's contents are:")
with file(filepath, 'r') as f:
    print(f.read())

Usage:
$ python 'Hello there Santhosh' something.txt
Your text input was:
Hello there Santhosh
The file's contents are:
<contents of something.txt here>

Note that the text is quoted; this is required if your text contains
spaces and/or shell special characters.

Cheers,
Chris
