What you are talking about is a very common technique. You write some code which abstracts the intent of an operation, but hides the implementation details. Then, you can change the implementation without all the places it's called from having to be aware of the change. So, it sounds like you want to write a function which accepts the two variable parts of the command, namely the username and password. That function will then use call(), or one of its variants, from the subprocess module (http://docs.python.org/2/library/subprocess.html) to execute the actual command, inserting all the other boilerplate. If, at some point in the future, you change which command you're calling, nothing but your function needs to change. -- https://mail.python.org/mailman/listinfo/python-list
Need help in writing some code so i can re-use it in every module or class
Hello Experts, I have requirement, like i want to use below command in python script. command --username username --password password Command line arguments now my requirement is i want to write some class so i can re-use command --username username --password password part via importing as module or class .. and re-use that in other module or classes .. so i dont have to write that in every module or classes .. Now why i wan to do this is ... currently command we are using is going to change in near future to command1, so i dont have go to every module and change that command if i have written single module or class and re-use it in other ?

Regards, DJ Hi, Have a look at http://docs.python.org/2/library/argparse.html Then create a module, for instance myParser, that defines the common paser, and in each of your scripts import that module and use the parser. *Untested code* myParser.py import argparse parser = argparse.ArgumentParser(description='Process some integers.') #then define the parser then in a script: script.py import myParser if __name__ == '__main__': args = myParser.parser.parse_args() # and so on...
