getting a variable into a bash script into a python script

Question

I have a python script I want to use for navigation. it returns a directory path ex /user/bin/dir/ I am making an ailas to it but I cant seem to pass it variables

this works in a shell

> cd `python ~doug/scripts/nv.py arg1
>>/user/bin/dir/

alias nav='cd python ~doug/scripts/nv.py $1' but this alias doesn't work

I would expect arg1 gets passed to $1

err cd python ~doug/scripts/nv.py arg1

bash aliases cannot take parameters; you want to use a shell function instead:

nav () {
    cd $(python ~doug/scripts/nv.py $1)
}

Depending on the script, you might want cd "$(python ~doug/scripts/nv.py "$@")" to pass all arguments instead of just the first, and also avoid trouble if the script outputs paths with spaces or glob characters.
