"- Python's dict is a fast unordered hashmap. However, if you need order-aware operations like C++'s std::map::lower_bound(), you're out of luck; Python's standard library doesn't have a tree implementation."
I'm fairly certain that in Python 3.7 and later standard library dictionaries are now ordered by default.
