Call Python script from bash with argument

Question

I know that I can run a python script from my bash script using the following:

python python_script.py 

But what about if I wanted to pass a variable / argument to my python script from my bash script. How can I do that?

Basically bash will work out a filename and then python will upload it, but I need to send the filename from bash to python when I call it.

Answer 1

To execute a python script in a bash script you need to call the same command that you would within a terminal. For instance

> python python_script.py var1 var2 

To access these variables within python you will need

import sys print sys.argv[0] # prints python_script.py print sys.argv[1] # prints var1 print sys.argv[2] # prints var2
