You will want to ask IPython questions on the IPython mailing list:
http://mail.scipy.org/mailman/listinfo/ipython-user
The reason you do not get the source is because there is no file that
contains functions defined in the interactive interpreter. %psource
uses the inspect module, and the inspect module explicitly only looks
in real files
but still:
In [218]: def f():
.....: return 42
.....:
In [219]: %save tmp.py 218
File `tmp.py` exists. Overwrite (y/[N])? y
The following commands were written to file `tmp.py`:
def f():
return 42
In [220]: !cat tmp.py
def f():
return 42
In [221]: %psource f
No source found for f
So? The function object f knows nothing about the file tmp.py. If you were to
import tmp and then ask for %psource tmp.f, it should work.
