First of all, please DO NOT post code with TABs in it.  In fact, you
shouldn't even be writing code with TABs -- TAB characters are obsolete
for new Python code.

I would write your code this way:

errors = []
for item in data:
    try:
        process(item)
    except ValidationError as e:
        errors.append(str(e))
if errors:
    raise MultipleValidationErrors(errors)
