If the dependant knows the function that instantiates the dependency, then there is no inversion of control whatsoever. it sounds like you are still looking at this with a java mental model there is definitely IoC here; resolving dependencies and deciding how and when to create the objects and how to wire them is still happening externally by the framework, but unlike java way of doing things (global container registry, reflection, type-driven DI), it's just done in more pythonic way following "zen" philosophy: explicit is better than implicit you declare what you need. fastapi will inspect function signatures, sees Depends, works out all sub-dependencies to resolve a dependency graph, handles scope (per request) and caching as needed, and use that to decide when to create it, in what order, where to injecting it, and when to clean it up. it might feel less "pure" for someone coming from Java background, but this is indeed IoC; fastapi DI is function-centric, more explicit, and less magical. It's a design choice :) plus tight coupling and testing is not an issue either, dependencies_overrides allows you to replace nodes in the dependency graph at any stage. More on reddit.com

Please ensure that: Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions You include any and all error messages in full - best also formatted as code block You ask clear questions You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

Because method time_explanation() is defined only once, on the class level - while property dog_time_dilation is separately stored for each object/instance of this class - Rocky, Rex, Clifford. You need to instruct time_explanation() on which specific dog should it be launched. It is true that in many programming languages this is simplified by hiding self in method signatures, and allowing direct access to instance variables (even without prefixing them with this.). But internally, they do pass self just like Python. More on reddit.com
