import sys
import readline
import rlcompleter

if sys.platform == 'darwin' and sys.version_info[0] == 2:
    readline.parse_and_bind("bind ^I rl_complete")
else:
    readline.parse_and_bind("tab: complete")

Save the file as name tab.py:

cd /Library/Python/2.7/site-packages
sudo vim tab.py

Then edit .bash_profile file:

echo "export PYTHONSTARTUP=/Library/Python/2.7/site-packages/tab.py" >> ~/.bash_profile
source ~/.bash_profile
