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
You should write this line to your
.bash_profile file, so that it's automatically executed when a new shell is started.
