The syntax and meaningful spaces are annoying. The dynamic typing is abused to hell in everything including the standard library. It has wacky paradigms like "exceptions instead of conditionals" or having "else" clause for loops.

It lacks decent packaging and by design cannot handle multiple versions of dependencies or perform metadata-only/declarative resolution. To resolve the dependencies of a Python package you need to install it. Many Python packages resolve their dependencies imperatively depending on the current system state. When you need binary dependencies like numpy it gets even worse since libpython doesn't have a stable ABI.

It is one of the most underdesigned languages but it holds a dear place due to being easier to translate from pseudocode to actual implementation. This resulted many academics to pick it up and write advanced math libraries in it.
