  > using exceptions for control flow is deprecated?

Exceptions are for the exceptional cases - the ones that mean normal operations are being suspended and error messages are being generated. Don't use them for control flow.

In Python, an iterator raises a StopIteration exception to indicate to the for loop that the iterator is done iterating.

In Python, the VM raises a KeyboardInterrupt exception when the user hits ctrl+c in order to unwind the stack, run cleanup code and eventually exit the program.

Python is a quite heavy user of exceptions for control flow.

Typically yes, but not in Python. In Python it is quite common and accepted, and sometimes even recommended as Pythonic to use exceptions for control flow. See iterators, for example.

I really dislike this too, but that’s how it is.
