Copy link 

ce = eval("digitalio.DigitalInOut(board.D" + str(ce) + ")")

I am not very experienced in meta-programming, so apologies if I misunderstood anything. But this looks concerning.
For example, you can run an arbitrary (buildin) function:

from apa102_pi.driver import apa102
apa102.APA102(ce="0),(print('testing')")

I feel like ce should be checked with .isnumeric() beforehand.
