`python-describe-symbol' can fail depending on the pager settings
detected by Python's pydoc module. If a pager is detected, the created
help buffer contains pager error messages about the terminal being not
fully functional instead of the desired documentation.
The problem can be avoided (in a not-threadsafe manner) by modifying
ehelp in etc/emacs2.py as follows:
def ehelp (name, imports):
"""Get help on string NAME.
First try to eval name for, e.g. user definitions where we need
the object. Otherwise try the string form."""
import pydoc
old = pydoc.pager
try:
pydoc.pager = pydoc.plainpager
locls = {}
if imports:
try: exec imports in locls
except: pass
try: help (eval (name, globals(), locls))
except: help (name)
finally:
pydoc.pager = old
This modification rebinds the pydoc.pager global variable to temporarily
disable the detected pager.

Neither python-describe-symbol nor etc/emacs2.py exist in Emacs any more
from 24.3 onwards. It looks like the replacement is
python-eldoc-at-point. This issue might be fixed now, but there is no
recipe to reproduce it, so I cannot say. Maybe you could try the latest
pretest 24.2.9x from http://alpha.gnu.org/gnu/emacs/pretest/ and let us
know.

Since the function has been removed, I think this issue can be
considered fixed. Thanks for asking.

That's not obvious to me, since there seems to similar code, but still
no reference to "pager" anywhere AFAICS.

The current python.el does not seem to use the pydoc module anymore
(which caused the reported problem). inspect.getdoc() seems to be used
instead. As far as I can see, inspect.getdoc() has a string-based
interface and does not print anything, so a pager is not involved.
