PyAPI: remove use of BaseException

BaseException was used as a catch-all in situations where it
didn't make sense and where "Exception" is more appropriate
based on Python's documentation & error checking tools,
`pylint` warns `broad-exception-caught` for e.g.

BaseException includes SystemExit, KeyboardInterrupt & GeneratorExit,
so unless the intention is to catch calls to `sys.exit(..)`,
breaking a out of a loop using Ctrl-C or generator-exit,
then it shouldn't be used.

Even then, it's preferable to catch those exceptions explicitly.
