--text follows this line--

Hi, I wrote a simple "Hello World" python script, and the output is
weird:

>>> import codecs, os;__pyfile =
codecs.open('''/var/folders/f9/y1xt5ytn02v2n7p8pk3_h4xw0000gn/T/py1281TtN''',
encoding='''utf-8''');__code =
__pyfile.read().encode('''utf-8''');__pyfile.close();os.remove('''/var/folders/f9/y1xt5ytn02v2n7p8pk3_h4xw0000gn/T/py1281TtN''');exec(compile(__code,
'''/Users/monibahmed/Documents/Python/people_class/hello_world.py''',
'exec'));
Hi
Hello World!
>>>

Any recommendation on how to fix this?

Thanks,
Monib

Perhaps you can figure out how to make Emacs' python code (see
__PYTHON_EL_native_completion_setup() in python.el) work properly with
a libedit based readline?

Otherwise, you can work around it by installing a GNU readline based
readline module:
