newbie question about PYTHONPATH

[Tim Hanson]

I am to the point in _Learning_Python_ where functions are introduced.

I decided to experiment by putting a function into a file and importing it
into Idle. Of course, Idle couldn't find it, so I executed the following
command in Bash:

PYTHONPATH=/home/foo/prog/learning_python
export PYTHONPATH
env | grep PYTHONPATH

~$PYTHONPATH=/home/foo/prog/learning_python

Idle still won't find it. I'm doing something wrong?

The best way I have found is to place that definition of your PYTHONPATH
in your .bash_profile in your home directory and export it from there.

PYTHONPATH=/home/foo/prog/learning_python

export PYTHONPATH

This way your PYTHONPATH is picked up each time you log on. You
might have to restart IDLE for the changes you mention below to take effect.

Yes but like this you overwrite it
export PYTHONPATH=/your/path:$PYTHONPATH

is much more safe to use

It's even safer to use
export PYTHONPATH=$PYTHONPATH:/your/path
