$.$ Consider the following code, and answer the questions below:

$1$ def someFunction$($text$,$ num$)$:

$2$ for i in range$($num$)$:

$3$ print$($text $*$ i$)$

$4$

$5$ # Main Program

$6$ star $=\text{'}*\text{'}$

$7$ number $=5$

$8$ someFunction$($star$,$ number$)$

$($a$)$ In this code, is the variable star used as a parameter, or an argument? Is text an argument

or a parameter?

$($b$)$ What is the difference between parameters and arguments?

$3.$ Trace the following code, writing the value assigned to each variable after each iteration of the

loop:

$1$ def my$\_$func$($x$,$ y$)$:

$2$ print$($x $+$ y$)$

$3$ return $($x $-$ y$)**2$

$4$

$5$ values $=[1,5,9,7,2,4]$

$6$ for i in range$($len$($values$))$:

$7$ a $=$ values$[$i$-1]$

$8$ b $=$ my$\_$func$($a$,$ i$)$

Iteration # $123456$

i Values

a Values

b Values
