I'm sorry, but this is garbage. There is no Python 4, even a planned such version. Guido has said that the damage cause by the (completely necessary) Python 3 transition was so great that we shouldn't do it again. All the new features you mention could be accomplished without a breaking change.

Conclusion: you simply made this all up, which means you got an AI to write it.

Shame, shame, shame on you. Lying is a sin. You lied to a lot of people.
