Easier:
def proclaimed_repr():
seen = False
def show_obj(obj):
nonlocal seen
if not seen:
seen = True
print("unexpected item in the bagging area!")
return repr(obj)
return show_obj
json.dump(f, default=proclaimed_repr())
If you don't care about "resetting" the marker, you can just use a
global or a default-arg hack:
def show_obj(obj, seen=[]):
if not seen:
seen.push(True)
print("unexpected item in the bagging area!")
return repr(obj)
json.dump(f, default=show_obj)
Either way, you can stick this function off in a utilities collection,
and then use it without fiddling with try/except.
