The word "automation" is on everyone's lips for a while. We need to perform tasks as fast as possible and we develop or use tools to automate as much as possible. Also because we are lazzy people (well, honestly, I am ;-), if you can solve annoying tasks with a few lines of Python, go ahead! But results must be controlled and validated. Expecially when you perform scans or vulnerability assessments. It's so easy to drop a device on a network with a bunch of tools and start to scan everything.
