No No NO! you cant just pass user input to system calls without validating it first (google sql injection for examples of the damage unsanitised input can cause, it is not just as SQL problem) it is just as easy so select a reasonably named function as a bad one option=raw_input('select your option :') if option =="1": install_java() if option =="2": install_other() alternatively you cold add your functions into a dictionary an call them from that opts={'1':install java,'2':install_other} option=raw_input('select your option :') opts[option] Poorly named functions are a major example of poor programming style. one of the fundamental pillars for python is readability! -- <knghtbrd> He's a about half the size of the others. <knghtbrd> But he's got a chainsaw. -- http://mail.python.org/mailman/listinfo/python-list
