"Python dictionaries, beginning in version 3.6, maintain the order of insertion of key-value pairs, marking a significant change since older versions were unordered."
"Before Python 3.6, dictionaries had no guaranteed order of items, leading to unpredictable outputs when items were printed or iterated upon."
Python dictionaries have undergone a significant evolution regarding their order of items. Prior to Python 3.6, dictionaries were unordered, meaning the insertion order of key-value pairs was unpredictable. However, with the release of Python 3.6, dictionaries started maintaining the order of insertion, ensuring that the order remains consistent for retrieval and iteration. This change derived from an implementation detail in CPython, making it a noteworthy distinction for developers when utilizing dictionaries.
