function caniuse()
{
    local domain="http://caniuse.com/"
    local query

    if [ $# -eq 0 ]; then
        open ${domain}
    else
        for term in "$@"; do
            query=$(python -c "import sys, urllib as ul; print ul.quote('${term}');")
            open "${domain}#search=${query}"
        done
    fi
}

I get an error when I try to use this.
Couldn't get a file descriptor referring to the console

Do I need to install the "open" command?
