Try installing gnureadline, as described in etc/PROBLEMS:

    *** In Inferior Python mode, input is echoed and native completion doesn't work.
    <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25753>

    This happens when python uses a libedit based readline module, which
    is the default on macOS.  This can be worked around by installing a
    GNU readline based module instead, for example, using setuptools

        sudo easy_install gnureadline

    And then rename the system's readline so that it won't be loaded:

        cd /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
        mv readline.so readline.so.bak

    See <https://pypi.python.org/pypi/gnureadline> for more details on
    installation.
