蟒蛇。从多个异常中提出异常

Question

我可以引发异常from另一个例外，以便提供其他信息，例如：

try:
    age = int(x)
except Exception as ex:
    raise ValueError("{} is not a valid age.".format(x)) from ex

有没有办法从多个例外来源？ e.g。

try:
    age = int(x)
except Exception as ex1:
    try:
        age = date_now().year - parse_date(x).year
    except Exception as ex2:
        raise ValueError("{} is not a valid age or date.".format(x)) from ex1 + ex2
