I need some help with syntax of the 'def' function.
I think that I understand the basic concept of the 'def' function, but I feel like I might need somethings cleared up. I just need a basic understanding of it, some help understanding why it's necessary in python, and some help understanding why, in this exercise (Learn Python: Functions/Parameters and Arguments), you need to 'define' power. I need someone to better explain it to me because it's a little bit confusing... I'd appreciate a little help! Thank you!
