emacs에서 ipython으로 python3 코드 실행시 Warning이 뜰 때

Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support readline, yet ‘python-shell-completion-native’ was t and "ipython" is not part of the ‘python-shell-completion-native-disabled-interpreters’ list.  Native completions have been disabled locally. 

위와같은오류가 뜬다면, 

python.el에서  python-shell-completion-native-turn-on-maybe를 찾아서 아래의 cond 마지막에서 lwarn부분을 주석처리 해주면 됩니다.
