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
