IPython + Python: Single Bash Command

The following is a simple Bash function you can paste into your bashrc file to start Python/IPython depending on the context.

~/.bashrc

function python {
    IPYTHON="/usr/bin/ipython"
    PYTHON="/usr/bin/python"

    if [[ -n $1 ]]; then
        $PYTHON $@
    elif [[ -e $IPYTHON ]]; then
        $IPYTHON
    else
        $PYTHON
    fi
}
