Is there something similar to the PHP autoloader in Python?

No, there is no such function. And in Python, you shouldn't attempt such operations. There is a good reason for autoloading in PHP, which is that PHP scripts are executed from scratch every time the page is loaded. The opcode might be cached, the file might be ready, but the main problem remains - importing another file actually means making sure its contents are loaded.

In Python's web service, your file is not reloaded every time it is read. If you import something, it will be imported for the life of the application. Autoloaders in Python are only used once, not on every request.

So, in PHP, autoloaders potentially enable you to skip unnecessary file loading costs. In Python, you only need to load things when the application starts, new requests do not need to load anything extra.
