TIL #143 – Resolve a lazy import manually

Learn how to work around the Python machinery to resolve an explicit lazy import manually. A couple of articles ago I wrote about how you could inspect a lazy import. Apparently, you can use a similar trick to check the attributes and methods that a lazy import has: >>> lazy import json >>> dir(globals()["json"]) ['__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'resolve'] Apart from a large number of dunder methods and dunder attributes, you'll find the method resolve. You can run help(globals()["json"].resolve) to get the help text on that method: Help on built-in function resolve: resolve() method of builtins.lazy_import instance resolves the lazy import and returns the actual object This shows that it's the method…
