 * - research extension points versus plugins
 *
 * from igor: two plugins A and B, both depend on the same library but use different versions, say
 * lib 1.0 and lib 2.0 when debugger hits a breakpoint inside a class from the library, IDE needs to
 * know which version of library the class comes from

* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:
