What a strange reading of what I wrote. Clearly I'm referring to the fact Bart is a beginner in Python. To show good faith in learning Python – if indeed that is what Bart wants, which I'm not convinced of given how much he prefers to talk about a different private programming language instead – then he should be taking advantage of the teaching resources that have been offered numerous times. > What exactly is the problem here?

The problem is that Bart simultaneously is a beginner at Python, and expresses astonishment that everyone shrugs when Bart's dreadfully-written code performs so badly. Good faith is contradicted by asserting knowledge of Python, complaining about how some deliberately non-idiomatic Python code is performing poorly, dismissing suggestions for improvement — specifically in the context of someone who admittedly knows so little about Python. -- \ “… one of the main causes of the fall of the Roman Empire was | `\ that, lacking zero, they had no way to indicate successful | _o__) termination of their C programs.” —Robert Firth | Ben Finney
