But you still haven't addressed the main objection here: that you're comparing two different undertakings. You've compared writing a small app in a high level language with learning a natural language. You could have just as easily said it isn't as hard as proving fermat's last theorem, or writing a novel, or composing a symphony. Thsse things also have a few elements in common with writing a short script in a high level language. But these comparisons don't mean a thing.
For a simple language such as python, you can learn most of the syntax very quickly. Vocabulary (e.g., libraries) takes a bit longer but still requires much less memorization. And you can always create things from scratch.
