Hi all,
I found a solution to fix the echo problem of the emacs python shell:
http://stackoverflow.com/questions/8060609/python-interpreter-in-emacs-repeats-lines
That is, in the Interior Python buffer, do
M-: (setq comint-process-echoes t) ;; or nil
Now, if I enter command directly in the interior python buffer, the command
is not echoed and this is what I want.
However, When I evaluate the python src code block in org-mode(by `C-c
C-c`), the problem persists. I notice every time I evaluate the block, I
see 'org_babel_python_eoe' in the interior python buffer.
I stumbled on a very strange emacs behavior. When I fiddled around, at
some point, I produced the correct answer as the manual. I thought I got
the right setup, but when I saved everything and restarted emacs, problem
persists. Will it be a sign of anything wrong?
What's even stranger is that: the evaluation for the first time gives
different results from the evaluation for the second time, on exactly the
same src_block:
This is what I got when I evaluation the code block for the first time:
-------------------------------------
#+BEGIN_SRC python :results output :session foo
x=100
print "hello"
2
print "bye"
#+END_SRC
#+RESULTS:
#+begin_example
x=100
print "hello"
hello
2
2
print "bye"
bye
#+end_example
-----------------------------------------------
-------------------------------------------------------
The following is what I got when I evaluate the same block again:
#+BEGIN_SRC python :results output :session foo
x=100
print "hello"
2
print "bye"
#+END_SRC
#+RESULTS:
: x=100
: print "hello"
: hello
: 2
: 2
: print "bye"
: bye
:

Notice that the prompt symbol ">>>" is in the result for the first
evaluation but not in the second evaluation.
