Python script running in linux

Question

I am having trouble trying to get this script to work. When I debug this code it will not read into the class or functions. The code will not execute properly. Has anyone know the problem here, Thanks

#!/home/build/test/Python-2.6.4

import os, subprocess

class mks_function:

 sandbox="new_sandbox"

 def mks_create_sandbox():  
  try:  
   retcode=call("si createsandbox" + "--no --hostname=bel --port=70 --user=user --password=1234 --populate --project=e:/project.pj --lineTerminator=lf new_sandbox", shell=True)  
   if retcode < 0:  
    print >>sys.stderr, "Child was terminated by signal", -retcode  
   else:  
    print >>sys.stderr, "Child returned", retcode  
 except OSError, e:  
    print >>sys.stderr, "Execution failed:", e  
    print "sandbox retVal="+retcode  
    print "Creating a new sandbox called "+sandbox+" "

Answer 1

Few things to check your code

• call should be subprocess.call
• better use full path when you call for example, /usr/bin/si createsandbox , you can check with which si in shell
• instead of concatenating the commands "si createsandbox" + "--no ..." , please use list ["/usr/bin/si","createsandbox --no ..."]
• you didn't import sys , but using it
• sandbox should be self.sandbox and def mks_create_sandbox(): should be def mks_create_sandbox(self):
• Use an IDE for example Ulipad .

Answer 2

Try put as the first line:

#!/usr/bin/env python

If you really need specific version of Python, setup your environment before running.

Possible problems:

• your code is never executed (it's like you define the class only). Use it in the file (names are misleading):

  if __name__ == '__main__': myObject = mks_function()

• show us how are you executing the code? Have you changed the permissions to be able to run the script?

  chmod +x filename.py

• or are you trying to start it as:

  python filename.py
