This could be just "if lst:", but I agree, LBYL is not Python's style
(and isn't always possible anyway).
You can at least squish it up onto less lines, which might look better:
try: lst[0] += 1
except IndexError: pass
Alternatively, you can use this style:
from contextlib import suppress
with suppress(IndexError):
lst[0] += 1
