Python is a fantastic language and these advanced techniques, which highlight controlling threads, processes, I/O, and logging, are pivotal to adding permanency to your scripts. There are a number of examples in the industry that help assess security, such as Sulley. This is a tool that automates the fuzzing of applications in an effort to help identify security weaknesses, the results of which can later be used to write Frameworks such as Metasploit. Other tools help harden security by improving a code base, such as Open Web Application Security Project's (OWASP) Python Security Project. These are examples of tools that started out to fit a missing need and gained strong followings. These tools are mentioned here as to highlight what your tools could become with the right focus.
Tip
As you develop your own tools, keep in mind what your goals are, start small, and add capabilities. This will help you make the project manageable and successful, and the little rewards related to small successes will push you to engage in bigger innovations. Finally, never fear starting over. Many times, code will lead you in the right direction once you realize that the manner in which you were doing something may not be the right fit.
