I think Python is considered anti FP for two reasons: when suggestions to add more FP features have been raised, Guido has fairly unambiguously rejected those features.

That’s all fine though. Python can do what Python wants. All else being equal, I’d prefer a little more functional flavor than Python has, but I won’t turn my nose up at writing Python if duty calls.

However I can barely think of another mainstream and high level language that is more anti-FP than Python.

And lambdas, in spite of popular opinion, have nothing to do with it ;-)

(Actually I can think of another language that is more anti-FP than Python and that would be Go ... people saying Go is “pythonic” have it right)
