title: Performance with global variables vs local
body: <p>I am still new to Python, and I have been trying to improve the performance of my Python script, so I tested it with and without global variables. I timed it, and to my surprise, it ran faster with global variables declared rather than passing local vars to functions. What's going on? I thought execution speed was faster with local variables? (I know globals are not safe, I am still curious.)</p>
