🔥TOP 5 New Python Alpha 5
At the beginning of 2022, a new version of Python was released - Alpha 5 (3.11). Main features:
• Improved debugging with the exception chain of their messages. Python 2022 is showing features with trace detection pointing directly to where the error occurs. Python 2 had a similar feature, but required the addition of context to the code, which made things more difficult. Now context is done automatically.
• Variable exception handling - you can now reduce dependency in different ways depending on what other exceptions it is associated with. The ability to use multiple exception operations with an explicit random exception for all. Just create a big try/except block with all possible exception names, and then add more exclude statements to it. It is for this purpose that a group of exceptions, which can be associated with grouping many different exceptions together and applying a single handler function, is only called if something occurs internally due to exceptional probability.
• Variadic Generics - now you can create functions that take a variable number of arguments (up to 22). It was necessary to define a characteristic that could take into account the magnitude of the transferred value each time. Variadic Generics in Python 3.6 allows you to select any number of options at once, which is useful when iterating multiple operations.
• CPython performance optimization. Changes to functions applied to calls and word lookups should reduce overhead, call by the C stack, speed up everything from developing object-oriented code to accessing data dictionaries.
• Simplify work in other languages such as JavaScript on top of Python through high performance and parallel computing.
