If you have some programming experience then there is one particular feature of Python that is likely to turn you off.

Whitespace matters. Indentation is significant.

This comes as a shock to many people who are used to it being meaningless. Most languages in common use designate code blocks with braces ({ ... }), or in some cases special keywords (e.g. Lua’s do/then ... end). If you want to write your program without any indentation whatsoever then it won’t stop you.

So having to pay attention to whitespace worries people. Puts them off trying Python. Makes them chafe at the thought of using it. Their freedom is being abridged!

This is really weird, since everyone agrees that consistent indentation is a good idea. In fact, it’s about the easiest and most effective thing you can do to make your code legible.

This is why objecting to syntactically meaningful whitespace in Python is a straw-man. All it’s doing is requiring you to not write unreadable and misleading code. In fact, if you have good habits already then you will never notice it. Ever.
