A small subset of the importlib module, described below. The repr() of a float x is shorter in many cases: it’s now based on the shortest decimal string that’s guaranteed to round back to x. As in previous versions of Python, it’s guaranteed that float(repr(x)) recovers x. Floa...
In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.

PEP 492 introduced support for native coroutines and async / await syntax to Python 3.5. A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to...

Python importlib resources. The importlib module can now be used to read “resources,” or binary artifacts shipped with a Python application such as a data file. This way, a developer can access those files through importlib’s abstractions, so it doesn’t matter if they’re stored in a ...
