In what version of python did dictionaries become ordered by default?
Python 3.7 introduced ordered dictionaries.
In previous versions of Python, dictionaries were unordered - the order of items was essentially random and not guaranteed.
From Python 3.7 onwards, dictionaries preserve insertion order by default - so the order you add keys/values to the dict will be retained when iterating etc.
This was done to aid predictability and avoid some performance pitfalls with assuming ordering and then having the dictionary reorganize its contents. The unordered nature of earlier Python dicts was partly for efficiency reasons.
I tried to import the library of Alexandria, but instead I got an error meesage? Know why that is?
