There are a couple of problems:
fixedPoint()– what’s that? Is this defined somewhere else?xin the function without having defined it.sqrt(), but the logic isn’t anywhere near something that would calculate the square root of anything.There is at least one inelegance:
tryit()). This is not a problem per se, but it doesn’t make much sense, and you’re relying on a local variableabeing defined here instead of passing that variable to a stand-alone function defined on the module level. It’s hard to tell what that function is supposed to be doing, though.tryit()isn’t a good function name.
