Hi,
If I do a Cython class
cdef class A:
def __iter__(self):
for i in range(5): yield i
then in the console the iterator works fine but not its string representation.
sage: a = A()
sage: iter(a)
KeyError Traceback (most recent call last)
<ipython-input-6-039e95d088f4> in <module>()
----> 1 iter(w)
/opt/sage_flatsurf/local/lib/python2.7/site-packages/IPython/core/displayhook.pyc
in __call__(self, result)
251 self.write_output_prompt()
252 format_dict, md_dict = self.compute_format_data(result)
--> 253 self.write_format_data(format_dict, md_dict)
254 self.update_user_ns(result)
255 self.log_output(format_dict)
/opt/sage_flatsurf/local/lib/python2.7/site-packages/IPython/core/displayhook.pyc
in write_format_data(self, format_dict, md_dict)
172 # newline, even if all the prompt separators are ''. This is the
173 # standard IPython behavior.
--> 174 result_repr = format_dict['text/plain']
175 if '\n' in result_repr:
176 # So that multi-line strings line up with the left column of
KeyError: 'text/plain'
Does anybody knows where the problem comes from?
