Fill in the gaps in the nametag function so that it uses the format method to return first$\_$name and the first initial of last$\_$name followed by a period. For example, nametag$("$Jane$",$ "Smith"$)$ should return "Jane S$."$

def nametag$($first$\_$name, last$\_$name$)$ :

return $."$ format $\}$first$\_$name, last$\_$name $[0])$

print $($nametag$("$Jane$",$ "Smith"$))$

# Should display "Jane S$."$

print $($nametag$("$Francesco$",$ "Rinaldi"$))$

# Should display "Francesco R$."$

print $($nametag$("$Jean$-$Luc", "Grand$-$Pierre"$))$

# Should display "Jean$-$Luc G$."$
