# Add auto-completion and a stored history file of commands to your Python
|
|
# interactive interpreter. Requires Python 2.0+, readline. Autocomplete is
|
|
# bound to the Esc key by default (you can change it - see readline docs).
|
|
#
|
|
# Store the file in ~/.pystartup, and set an environment variable to point
|
|
# to it, e.g. "export PYTHONSTARTUP=/max/home/itamar/.pystartup" in bash.
|
|
#
|
|
# Note that PYTHONSTARTUP does *not* expand "~", so you have to put in the
|
|
# full path to your home directory.
