19. API - Exceptions
The following exceptions are defined by Lanner PSP. Please note that multiple inheritance is heavily used in the exception hierarchy to make testing for exceptions easier. For example, to capture any exception generated by Lanner PSP’s code:
from lannerpsp import *
led = LTEStressLED()
try:
led.set_strength(200)
except PSPError:
print("A Lanner PSP error occurred")
Since all Lanner PSP’s exceptions descend from PSPError
, this will
work. However, certain specific errors have multiple parents. For example, in
the case that an out of range value is passed to percent
you
would expect a ValueError
to be raised. In fact, a
PSPInvalid
error will be raised. However, note that this
descends from both PSPError
(indirectly) and from ValueError
so you can still do the obvious:
from lannerpsp import *
led = LTEStressLED()
try:
led.set_strength(200)
except ValueError:
print("Bad value specified")
