python-3.x - Python 3.5 - Quandl 错误处理

Question

试图弄清楚如何处理错误：

quandl.errors.quandl_error.NotFoundError: (Status 404) (Quandl Error QECx02) You have submitted an incorrect Quandl code. Please check your Quandl codes and try again.

这是我想要异常的代码片段：

            source = Q.get(query_site, authtoken=secret)
            df = df.join(source, how='outer')

break如果我得到错误，我想退出。我的except陈述会怎样？我试过NotFoundError了，但似乎没有用。

Answer 1

处理NotFoundError

from quandl.errors.quandl_error import NotFoundError

try:
    source = Q.get(query_site, authtoken=secret)
    df = df.join(source, how='outer')
except NotFoundError as e:
    print('error: {} '.format(str(e)))
