First, create a new file called .pythonstartup.py in your home directory. Put the following script in it: try: import readline except ImportError: print("Module readline not available.") else: import rlcompleter readline.parse_and_bind("tab: complete") The parentheses around the string ensure that it works with both Python 2 and Python 3. Every time the interactive interpreter is started, it executes a script defined in $PYTHONSTARTUP, if there is one. To set it to execute the above script, type export PYTHONSTARTUP=".pythonstartup.py" You should write this line to your .bashrc or .bash_profile file, so that it's automatically executed when a new shell is started.
