"**" in python

[Skip Montanaro]

I want to add one more thing to the other responses. People new to Python
often seem unaware that being an interpreted language, often the best way
to figure something out is to simply try it at the interpreter prompt. The
OP saw "var ** 2" in done code. The most obvious thing to me would have
been to type

var = 42
var ** 2

and see what happened. It's unlikely to trigger a nuclear meltdown, or even
crash the interpreter.
