Too much indentation, and worse, indentation that changes based on a
distractingly irrelevant quantity: the length of the first line. I
prefer::
excessblk = (
Block(total - P.BASE, srccol, carry_button_suppress=True)
if total > P.BASE else None)

If the expression assigned in the ‘else’ branch were also quite long,
I'd say yes::
excessblk = (
Block(total - P.BASE, srccol, carry_button_suppress=True)
if total > P.BASE
else Block(total, srccol, carry_button_suppress=False))
