Python-twilio api 错误？

Question

我正在使用 twilio-python 并且正在学习本教程: http://readthedocs.org/docs/twilio-python/en/latest/usage/twiml.html?highlight=nest

但是当我尝试这个时:

from twilio import twiml

r = twiml.Response()
r.say("hello")
with r.gather(finishOnKey=4) as g:
    g.say("world")
print str(r)

但是我明白了:

AttributeError: __exit__

有什么想法吗？

Answer 1

它们似乎与 with 语句并不兼容。试试这个:

from twilio import twiml

r = twiml.Response()
r.say("hello")
g = r.gather(finishOnKey=4)
g.say("world")
print str(r)

这是我得到的:

>>> from twilio import twiml
>>> 
>>> r = twiml.Response()
>>> r.say("hello")
<twilio.twiml.Say object at 0x1098d05d0>
>>> g = r.gather(finishOnKey=4)
>>> g.say("world")
<twilio.twiml.Say object at 0x1098d0950>
>>> print str(r)
<?xml version="1.0" encoding="UTF-8"?><Response><Say>hello</Say><Gather finishOnKey="4"><Say>world</Say></Gather></Response>
