What Is The Default Binding To The `__import__` Attribute Of The Module `builtin`?

From Python in a Nutshell Custom Importers An advanced, rarely needed functionality that Python offers is the ability to change the semantics of some or all import and from

Solution 1:

1. Yes, that's a typo in the book. In Python 2 the same module is named __builtin__ (no s), in Python 3 it is named builtins.

2. builtins.__import__ is a distinct function from importlib.__import__. If you are going to rebind builtins.__import__, save a reference.

   • builtins.__import__ is implemented in C, and essentially calls the C-API PyImport_ImportModuleLevelObject function.

   • importlib.__import__ is a pure-Python function. The goal of importlib is to provide a pure-python implementation of the import machinery so it can be hacked on more easily, and this function is no exception.
