It's been a while since I touched Python (thankfully), but there's also:

- The hideous __method__ and _private conventions

- A friend of mine was complaining about the implicit string concatenation: ["foo" "bar", "baz"] whoops forgot a comma and now there's a very hard to find bug

- pyc and pyo files littering the filesystem after running (yes, only a minor nuisance)

- import anywhere, the ugly __name__ = "main" hack

- GIL, reference counting GC, abysmal performance in general

- Dynamic typing, which is probably my most major complaint but I realize opinions differ
