Seriously, when my friend first told me about PythonAnywhere(TM), I actually refused to believe him, because I couldn't imagine that such an amazingly awesome tool could actually exist. I actually disagreed with him quite forcefully, and it led to a rather heated argument, and I'm afraid our friendship suffers to this day.
But what's the loss of a friend compared to the gain of such an amazing tool? Now that I've used PythonAnywhere(TM), I am actually happy to go to my grave, and leave a smiling corpse, resting soundly in the knowledge that such a website exists.
I have seen perfection. And its name - is PythonAnywhere(TM)
