Python 3.6 is a high-level programming language that was released in December 2016. It introduced several new features, including formatted string literals, also known as f-strings, which make it easier to embed expressions inside string literals. This version also improved the performance of dictionaries and added type hints, enhancing code readability and maintainability. One of the notable enhancements in Python 3.6 is the support for asynchronous programming through the `async` and `await` keywords. This allows developers to write more efficient code for I/O-bound applications. Python 3.6 is part of the broader Python ecosystem, which is widely used in web development, data analysis, and artificial intelligence.
