Can some one help me with the syntax, how to call 'x' function from a shell script. The challenge here is, from shell script need to pass a,b dynamically.

your suggestion greatly appreciated.

Python Code:

def x(a,b):
 '''x(a,b) --> [a,b]'''
 return [a,b]
def add(a,b):
 '''add(a,b) --> a+b'''
 return a+b
def test():
 '''test code for all modules'''
 print "testing x..."
 print x(1,2)
 print x('a','b')
 print x([1,2,3],[4,5,6])
 print "testing add..."
 print add(1,2)
 print add('a','b')
 print add([1,2,3],[4,5,6])
 return

  • @MadPhysicist, but that answer is old and not Python3 compliant Commented Dec 8, 2015 at 21:19
  • @JohnLaRooy this isn't a Python3 question, and $ python on *nix should always run python2. If you'd like to update the answer, do so on the duplicate. Commented Dec 8, 2015 at 21:25

    @AdamSmith, Arch linux already defaults to python3 and Ubuntu 16.04 is planning to move away from python2.., PEP0394 says "for the time being..." Commented Dec 8, 2015 at 21:35
  • @JohnLaRooy is that so? Awesome! Python2 has been a long-rotting corpse as far as I'm concerned. Commented Dec 8, 2015 at 23:21

If you save the file foo.py, you can run this from the shell

python -c "import foo; print(foo.x(1, 2))"

The result can be read from stdout.

thanks for response.. But I need to pass the param dynamically . Like python -c "import foo; print(foo.x(${var1}, ${var2}))"
So do that. What is stopping you?
This is not working on our Red Hat Enterprise Linux Server release 5.11, please help me to identify the alternative
