With those inputs, calculate a score for the student based on assignments being worth

of their final grade and tests being worth a total of

of the grade. Within each group, all the grades are equally weighted.

Thus, calculate the final grade by the formula:

$\backslash$text$\{$final$\_$grade$\}=($a$1+$ a$2+$ a$3+$ a$4)/4*0\mathrm{.}45+($t$1+$ t$2)/2*0\mathrm{.}55$

Write an f$-$string to format the final grade in a percentage. Hint: Refer to $($Exercise $14$ on the page$)[$#$].$

Print out the f$-$string on screen
